Abstract

Abstract Lithium and copper 3-trimethylsilylmethyl dienolate anions derived from easily available 3-trimethylsilylmethyl-3-butenoic acid and its methyl ester underwent regio-and stereo-selective alkylation. α-Alkylated products were readily transformed to 3-alkylated 2- methallylsilanes by pyrolysis.
