The regio- and stereoselective syntheses of the (Z)- and (E)-stereoisomers of some 1-trimethylsilyl-2-(hetero)arylethenylstannanes and 1-trimethylsilyl-2-alkylethenyltrimethylstannanes are reported.  The strategy followed involves: a) stereoselective cis- and trans-hydroalumination of the corresponding 1-alkynylsilanes; b) conversion of the stereodefined 1-alkenyl-1-silylalanes so obtained into the corresponding aluminates; and c) the cuprous iodide-triethyl phosphite complex mediated reaction of these aluminates with trimethyltin chloride.

Abstract

The regio- and stereoselective syntheses of the (Z)- and (E)-stereoisomers of some 1-trimethylsilyl-2-(hetero)arylethenylstannanes and 1-trimethylsilyl-2-alkylethenyltrimethylstannanes are reported.  The strategy followed involves: a) stereoselective cis- and trans-hydroalumination of the corresponding 1-alkynylsilanes; b) conversion of the stereodefined 1-alkenyl-1-silylalanes so obtained into the corresponding aluminates; and c) the cuprous iodide-triethyl phosphite complex mediated reaction of these aluminates with trimethyltin chloride.
