Here we present a comprehensive study on the [3+2]-cycloaddition of thiocarbonyl ylides with a wide variety of alkenes and alkynes. The obtained dihydro- and tetrahydrothiophene products serve as exceptionally versatile intermediates providing access to thiophenes, dienes, dendralenes, and vic-quarternary carbon centers. The use of high-pressure conditions enables thermally unstable, sterically encumbered or moderately reactive substrates to undergo the cycloaddition under mild conditions, thereby increasing the yield by up to 58%. In addition, we showcase its utility by the formal syntheses of the pharmaceuticals NGB 4420 and tenilapine.

Kaolinite clay found its application in medicine, in toothpaste, in cosmetic and as a food additive. Recently, a specially formulated spray is used in fruit and vegetable production to repel the insects and prevent sunburn. Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. 2-Substituted benzimidazoles have been used as selective neuropeptides YY, receptor antagonists, antitumor, antivirus, antimicrobial, antioxidant, antiparasitic, antihelmintics, antiproliferative, anti-HIV, anticonvulsant, anti-inflammatory, antihypertensive, antineoplastic, analgesicand antitrichinellosis, topoisomerase IV inhibitors, potent inhibitors of TiE-2 and VEGFER-2 tyrosine kinase receptor, and 5-HT3 antagonists. 2-Substituted benzimidazoles are prepared via condensation of o-phenylenediamines and aldehydes. In this article, we have used Kaolin-SO3H nanoparticles for the synthesis of 2-substituted benzimidazoles under mild reaction conditions. The structure of products were identified by FT-IR, H-1-NMR and C-13-NMR. This method has the advantages of high yields, short reaction times and easy work-up.

Atroposelective arene formation is an efficient method to build axially chiral molecules with multi-substituted arenes. Reported here is an organocatalyzed atroposelective arene formation reaction by an N-heterocyclic carbene (NHC) catalyzed formal [4+2] cycloaddition of conjugated dienals and alpha-aryl ketones. This study expands the synthetic potential of NHC organocatalysis and provides a competitive pathway for the synthesis of axially chiral ligands, catalysts, and other functional molecules.

The mechanism of most mechanofluorochromic (MFC) materials is related to a noncovalent change in aggregate packing. It is still a challenge to clarify the respective effects of molecular conformation and intermolecular interaction on the MFC performance. Herein, a new (9-anthryl)vinyl derivative APYB with a polymorph-dependent multicolor-switchable MFC property is reported. APYB has only one torsion unit in the molecule configuration and could form four different crystal phases (APYB-a, APYB-b, APYB-c, and APYB-d). Furthermore, all polymorphs are MFC-active. Therefore, it provides a rare and direct case to correlate the aggregate packing with MFC performance. The solid-state emission could be finely tuned from 465 to 500 nm by virtue of polymorphism. Crystal structure analyses and optical studies reveal that an increasing twist angle could result in a blue shift in the fluorescence spectrum and a high-contrast MFC performance. In contrast, strong intermolecular interactions could lead to high emission efficiency and amorphization difficulty during the mechanical grinding. A tricolor-switchable MFC phenomenon was observed for APYB-a, while both APYB-b and APYB-d display a reversible bicolor-changing MFC behavior. As for APYB-c, mechanical grinding only causes a minor change in the emission spectrum. However, two competitive reverse transformation routes were found when treating the ground sample with organic solvent vapor. XRD analyses show that the MFC mechanism for APYB-a, APYB-c, and APYB-d is a crystal-to-amorphous transformation, while only partial amorphization was observed in the MFC behavior of APYB-b. The acidochromism effects of APYB-a and APYB-b were also investigated. They also display multicolor changes due to the polymorphic nature of APYB. Interestingly, in the deprotonation process, NH3 vapor could induce a different transformation route and color change from NEt3.

Highly accelerated inverse-electron-demand strain-promoted alkyne-nitrone cycloaddition (IED SPANC) between a stable cyclooctyne (bicyclo[6.1.0]nonyne (BCN)) and nitrones delocalized into a C-a-pyridinium functionality is reported, with the most electron-deficient pyridinium-nitrone displaying among the most rapid cycloadditions to BCN that is currently reported. Density functional theory (DFT) and X-ray crystallography are explored to rationalize the effects of N- and C-a-substituent modifications at the nitrone on IED SPANC reaction kinetics and the overall rapid reactivity of pyridinium-delocalized nitrones.

A new series (6) of C-5-curcuminoid derivatives (2E,6E-2,6-dibenzylidene-4-hydroxycyclohexanones) is described here with their evaluation for in vitro antiproliferative activities. Evaluation of 31 compounds against human A2780 (ovarian), C33A (cervix) and MDA-MB-231 (breast) cancer cell lines was performed to obtain structure activity relation data. The best performer was (2E,6E)-2,6-bis(3 ‘-nitrobenzylidene)-4-hydroxycyclohexanone (6h) with IC50 values of 0.68 mu M (A2780), 0.69 mu M (C33A) and 0.92 mu M (MDA-MB-231) compared to cisplatin with 1.30 mu M, 3.69 mu M and 19.13 mu M, respectively. According to calculated physicochemical properties some members in series 6, namely (2E,6E)-2,6-bis[(4 ‘-pyridinyl)methylene]-4-hydroxycyclohexanone (6p) [IC50 = 0.76 mu M (A2780), 2.69 mu M (C33A), 1.28 mu M (MDA-MB-231)] seem to have improved bioavailability compared to curcumin. Selected members of series 6 were involved in circular dichroism spectroscopic measurements in order to determine their interaction with natural DNA. Based on these data, we conclude that these derivatives do not bind to DNA in vitro. A proposal is summarized based on mass spectrometric assessment for fingerprint analysis in biological research of such C-5-curcuminoids.

Tetrahydrophthalazine derivatives have found important applications in pharmaceutical research, but existing synthetic methods are unable to access them regio- and stereoselectively. Here, a new approach is presented that addresses these challenges by utilizing a 6-endo-trig radical cyclization in the key step. The desired tetrahydrophthalazines can be accessed in high yields (55-98 %) and high diastereoselectivities for the trans-product (>95:5) starting either from readily accessible hydrazones, or from the corresponding aldehydes and substituted Boc-hydrazides in a one-pot process. The synthetic versatility of the tetrahydrophthalazine core was demonstrated by its straightforward conversion to dihydro-phthalazines, phthalazines, or pyrazolo dione derivatives. Furthermore, the N-N bond was reduced to afford a new route to 1,4-diamines.

Leishmaniasis has affected a wider part of population around the globe. Most often, the existing regiments to battle against leishmaniasis are inadequate and limited. In our ongoing efforts to develop new leishmanicidal agents, we have synthesized a series of novel and symmetrical bis-Schiff base-disulfide hybrids 1-27. Intermediate disulfide was synthesized from corresponding 2-aminothiol followed by reacting the coupled adduct with various aromatic aldehydes. All these compounds showed outstanding inhibition when compared with standard (Table 1). Out of twenty seven analogues, twenty two analogues i.e. 1-5, 7-13, 17-21, 23-27 analogues showed excellent inhibitory potential with EC50 values ranging from 0.010 +/- 0.00 to 0.096 +/- 0.01 mu M while five compounds i.e. 6, 14-16, and 22 showed good inhibitory potential with EC50 values ranging from 0.10 +/- 0.00 to 0.137 +/- 0.01 mu M when compared with the standard Amphotericin B. Structure-activity relationship has been established while molecular docking studies were performed to pin the binding interaction of active molecules. This study will help to develop new antileishmanial lead compounds.
