Properties and Reactions of Ring-Deactivated Deuterated Hydroxymethylpyrroles
摘要:
[GRAPHICS]Chlorination and mesylation at the hydroxymethyl position of deuterium-labeled N-substituted 2-(hydroxymethyl)pyrroles has been shown to occur with some involvement of a highly reactive azafulvenium species. An electron-withdrawing camphorsulfonyl substituent on nitrogen provides a chiral handle for direct analysis of the stereochemical outcome of the reactions by H-1 NMR.

design and synthesis of N-heteroaryl-fused vinyl sultams as templates for programming chemical reactions on vinyl sultam periphery or (hetero)aryl ring is described. The key features include rational designing and sustainable synthesis of the template, customized reactions of vinyl sultams at C═C bond or involving N–S bond cleavage, and reactions on the periphery of the heteroaryl ring for late-stage
