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.
