Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Mokhtari, Tayebeh Sattaei, once mentioned the application of 503615-03-0, Name is 3-Morpholino-1-(4-nitrophenyl)-5,6-dihydropyridin-2(1H)-one, molecular formula is C15H17N3O4, molecular weight is 303.31, MDL number is MFCD19440872, category is pyridine-derivatives. Now introduce a scientific discovery about this category, Computed Properties of C15H17N3O4.
Polar [3+2] cycloaddition of isatin-3-imines with electrophilically activated heteroaromatic N-ylides: Synthesis of spirocyclic imidazo[1,2-a]pyridine and isoquinoline derivatives
A new synthesis of spiro[imidazo[1,2-a]pyridine-2,3′-indoline]-2′-ones 3a-f and spiro[imidazo[1,2-a]isoquinoline-2,3′-indolin]-2′-ones 5a-d, respectively by polar [3 + 2] cycloaddition reactions of isatin-3-imines with pyridinium and isoquinolinium ylides which are derived from 2-bromoacetophenone, 2,4′-dibromoacetophenone or methyl bromoacetate is described. These cycloaddition reactions consist of the nucleophilic attack of the heteroaromatic N-ylides on isatin-3-imine derivatives. The salient features of these processes include operational simplicity, high yields, and easily accessible starting materials. In addition, Density Functional Theory (DFT) calculations at the M06-2X/6-31 + G(d) level have been performed to investigate the possible transition states and products. The theoretical results are in good agreement with the experimental findings and show that the product 3a is the most stable product and is formed through a kinetically feasible pathway.
