Herein, a highly regioselective domino skeletal-expansion process that transforms 2-aminothiazolidinone into six-membered S,N-heterocycle is developed with the aid of TMS-azide in hexafluoroisopropanol (HFIP) at ambient temperature. Functioning of the C2 tertiaryamine as latent reactive group on thiazolidinone moiety was the key to this development, which allowed relay substitution with azide and

efficient protocol for synthesis of thioamides was developed via the microwave-assisted iodine-catalyzed oxidative coupling of dibenzyl(difurfuryl)disulfides with amines. This process is scalable and tolerates a wide spectrum of amines to deliver the corresponding products in moderate to excellent yields in 10 minutes, providing a cheap and rapid approach to thioamides.

Thioamides can be generated at 100 degrees C in high yield through the reaction of 1,2-dibenzyldisulfane with difurfuryldisulfide using iodine as oxidant and DMSO as solvent. The protocol is metal- and additive-free, providing a convenient and economical way for the synthesis of various kinds of thioamides under mild conditions.
