Synthetic approaches towards 4-(silylmethyl)-2-azetidinones
摘要:
Differently substituted 4-(silylmethyl)-2-azetidinones were prepared starting form the corresponding 4-acetoxy-2-azetidinones with silylmethylmagnesium chlorides. The same kind of beta-lactams were synthesized ''via'' cycloaddition of allylsilanes and chlorosulfonyl isocyanate (CSI).
