of the previously used tetrahydrofuran has allowed the synthesis in high yield of enamines of acylsilanes (2) from cyanohydrins (1) by reductive silylation with Me3SiCl/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 Me2C=C(SiMe3)NH2, which was surprisingly stable. Its ready
