Thioamidoalkylation of 1,3-dicarbonyl compounds, enol silyl ethers, and enamines
Novel syntheses of β-thioamido ketones via thioamido-alkylations of malonates, β-keto esters, β-diketones, enol silyl ethers, and enamines with N-(α-thioamidoalkyl)benzotriazoles are described. Georg Thieme Verlag Stuttgart.

A GENERAL METHOD FOR THE N-ALKYLATION OF THIOAMIDES.
Thioamides are N-alkylated in a two-step procedure: (i) Reaction with an aldehyde and benzotriazole yields an adduct which is (ii) reduced to the N-alkylthioamide by NaBH4.
