                                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).
