Dunn, A. D. published the artcile< Synthesis of new thiopyranopyridines>, Quality Control of 33402-75-4, the main research area is thiopyranopyridinecarboxylate; photochem bromination pyridinecarboxylate; bromomethylpyridinecarboxylate preparation substitution thioglycolate.
Thiopyranopyridinecarboxylates I and II (X, Y = CH, N; R = OH, NH2) are prepared from pyridine esters (e.g., III; R1 = Me, R2 = CO2Me; R1 = CO2Me, R2 = Me) and nitriles (e.g., III; R1 = Me, R2 = CN) by photochem. bromination, followed by substitution reaction of the resulting bromomethyl derivative with HSCH2CO2Me, and then base-induced intramol. cyclocondensation.
Journal fuer Praktische Chemie (Leipzig) published new progress about Cyclocondensation reaction, intramolecular. 33402-75-4 belongs to class esters-buliding-blocks, and the molecular formula is C8H9NO2, Quality Control of 33402-75-4.
