Abstract

Abstract The use as solvent of hexamethylphosphortriamide instead of the previously used tetrahydrofuran has allowed the synthesis in high yield of enamines of acylsilanes (2) from cyanohydrins (1) by reductive silylation with Me 3 SiCl/Li. Protodesilylation of 2a (R= R′= Me) by HCl gas in dry diethyl ether or by trimethylchlorosilane in methanol gave, after neutralization, a quantitative yield of the enamine Me 2 C= C (SiMe 3) NH 2, which was ...
