A strategy for the rapid synthesis of 3-substituted N-sulfonyl pyrazoles via p-TSA-promoted cyclization reactions of sulfonyl hydrazines with N,N-dimethyl enaminones has been developed. This method achieves both the formation of pyrazole ring and the cont
SYNTHESIS OF ADAMANTANE DERIVATIVES. 57. FACILE GENERATION AND CYCLOADDITION REACTIVITY OF N-PHENYLSULFONYL-1- AND -2-ADAMANTYLNITRILIMINES VIA BASE-INDUCED DEHYDROCHLORINATION OF N-(PHENYLSULFONYL)-1- AND -2-ADAMANTANECARBOHYDRAZONYL CHLORIDES
