Methyl N-phenyl ethanimidothioate 1 and its α-silylated homologue 2 are metallated into lithiated enaminates which can be regioselectively mono-alkylated at -78°C on the α-carbon atom. Imidothioester 2, treated at higher temperatures by 2 equivale

Convenient syntheses of S-aryldithioesters and thioamides are described: thus, thiols and amines are readily thioacylated with the S-borondithioester formed in situ, by the mild reaction of a dithioacid with 9-BBN.

Lithiated methyl N-phenyl-2-trimethylsilylethanimidothioate is regioselectively C-alkylated at –78 °C but, at a higher temperature in the presence of 1 equiv. of butyllithium, it is converted into a lithiated ketenimine which can be protonated or

Ethenamine 1 and its methyl derivatives 2 – 7 have been synthesized from the adducts 8 – 14 by a retro-Diels-Alder reaction under flash thermolytic conditions. The primary enamines 1 – 4 have been identified (IR, 1 H and 13 C NMR) in a pure sta

Enethiolizable β-oxidithioesters allowing the succesive formation of carboncarbon bonds at the carbonyl and at the thiocarbonyl sites, are precursors of α-unsaturated dithioesters and can be used as a 3 d 1 or a 3 a 1 synthons.
