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.

Synthetic elaboration of N-substituents in thioamides

N-(Benzotriazol-1-ylmethyl)arylthioamides, readily prepared from arylthioamides, formaldehyde and benzotriazole, undergo lithiation followed by reactions with alkyl halides, aldehydes and ketones to introduce the expected N-substituents into the N-methylene group. Subsequent displacements of the benzotriazolyl group by Grignard reagents, alkoxide or thioalkoxide anions provide general access to a wide variety of N-substituted thioamides in good yields.

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.
