Trimethyl(propargyl)silane is suitable for use in the synthesis of diverse end-functionalized (ω-carboxyl, ω-hydroxy, ω-methyl-vinyl, ω-trimethylsilane, and ω-glycidyl-ether) via ′′click′′ reaction. It may be used in the synthesis of γ-allenyl-GABA (γ-aminobutyric acid), via Lewis acid mediated reaction with ω-ethoxy lactams.
