Desulfurization of sultams with simultaneous methylenation
摘要:
Alkylation of gamma- and delta-sultams with (iodomethyl)trimethylsilane followed by treatment of the resultant silanes with tetrabutylammonium fluoride gave rise to sulfur-free unsaturated amines. In particular, N-THP substituted sultams were found to be useful substrates for the alkylation event. A corresponding one-pot transformation involving sultam alpha-alkylation with (iodomethyl)magnesium chloride is also reported. (c) 2007 Elsevier Ltd. All rights reserved.
