Triazolopyridines. Part 11. Ylides derived from 2-Acylmethyltriazolopyridinium salts.
Abstract Ylides derived from 2-acylmethyltriazolopyridinium salts (2a) -(2c) react with methyl or ethyl propiolate and with dimethyl acetylenedicarboxylate to give ylides (3a)–(3e), (6) or (7). In some cases 1:2 adducts are formed, shown to be the novel ylides (8a)–(8d); an X-ray diffraction confirms structure (8a).
Triazolopyridines. Part 27.1 the preparation of novel 6,7-dihydro[1,2,3] triazolo[1,5-a]pyridines
A very efficient synthesis of the unknown family of 6,7-dihydro[1,2,3]triazolo[1,5-a]pyridines from [1,2,3]triazolo[1,5-a]pyridines have been developed, and a mechanism for their formation has been proposed. Their behaviour with NBS to give 4,5-dibromo substituted-4,5,6,7-tetrahydro-[1,2,3]triazolo[1,5-a]pyridines is studied.
