Abstract:Alkylation of γ- and δ-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 α-alkylation with (iodomethyl)magnesium chloride is also reported.
Keywords:Alkenylation   Alkylation   Desulfurization   Sultams
