Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 144750-52-7, Name is Methyl 2-(2-chlorophenyl)-2-(4,5-dihydrothieno[2,3-c]pyridin-6(7H)-yl)acetate hydrochloride. In a document, author is Dmitrienko, Anton, introducing its new discovery. Category: pyridine-derivatives.
Selective Cross-Coupling of Unsaturated Substrates on Al-I
The Al-I compound NacNacAl (1, NacNac = [ArNC(Me)CHC(Me)NAr](-), Ar = 2,6-iPr(2)C(6)H(3)) serves as a template for the chemoselective coupling between carbonyls (benzophenone, fenchone, isophorone, p-tolyl benzoate, N,N-dimethylbenzamide, (1-phenylethylidene)aniline) and pyridine. With the CH-acidic ketone (1R)-(+) camphor, the reaction affords a hydrido alkoxide compound of Al, formed as the result of enolization, whereas an enolizable imine, (1-phenylethylidene)aniline, and the bulky ketone isophorone, still chemoselectively couple with pyridine. In contrast, reaction with the ester p-tolyl benzoate results in cleavage of the ester bond together with replacement of the alkoxy group by a hydrogen atom of the pyridine moiety. This study demonstrates that for carbonyl substrates featuring phenyl substituents, the reaction proceeds via intermediate formation of eta(2)(C,X)-coordinated (X = O, N) carbonyl adducts, whereas the reaction of 1 with (R)-(-)-fenchone in the absence of pyridine leads to CH activation in the pendant isopropyl group of the Ar substituent of the NacNac ligand.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 144750-52-7 help many people in the next few years. Category: pyridine-derivatives.
