N-TRIMETHYLSILYL DERIVATIVES OF THIOLACTAMS IN THE SILYL VERSION OF N-AMIDO- AND N-SULFONAMIDOALKYLATION

Sergeev, V. N.,Artamkin, S. A.,Baukov, Yu. I.

, p. 1598 - 1601 (2007/10/02)

N-Trimethylsilylthiolactams react with N-chloromethyllactams and -sulfonamides to give the corresponding N-amido- and N-sulfonylamidomethyl derivatives of thiolactams in fairly high yields. By contrast, products of addition of N-trimethylsilylthiolactams to aldehydes do not react as amidoalkylating agents with N-trimethylsilyllactams.
