摘要：
Reactions of pyrazolo[1,5-a]pyridines with Eschenmoser's salt, activated alkenes and alkynes, and chlorosulfonyl isocyanate provided general routes to 3-substituted pyrazolo[1,5-a]pyridines such as 3-dimethylaminomethyl- and 3-(2-nitroethyl)pyrazolo[ 1,5-a]pyridines, 1-phenyl-3-(pyrazolo[1,5-a]pyrid-3-yl)-2-propen-1-ones, 4-(pyrazolo[1,5-a]pyrid-3-yl)-3-buten-2-one, pyrazolo[1,5-a]pyridine-3-carboxamide, and pyrazolo[1,5-a]pyridine-3-carbonitrile.
