o-Iodoxybenzoic Acid Mediated Oxidative Desulfurization Initiated Domino Reactions for Synthesis of Azoles
摘要:
A systematic exploration of thiophilic ability of o-iodoxybenzoic acid (IBX) for oxidative desulfurization to trigger domino reactions leading to new methodologies for synthesis of different azoles is described. A variety of highly substituted oxadiazoles, thiadiazoles, triazoles, and tetrazoles have been successfully synthesized in good to excellent yields, starting from readily accessible thiosemicarbazides, bis-diarylthiourea, 1,3-disubtituted thiourea, and thioamides.

New application of sulfated tungstate, a mildly acidic solid inorganic acid, as reusable heterogeneouscatalyst for efficient Kindler reaction, a three component reactions of aldehydes, amines and sulfur, for synthesis of thioamides is discussed.

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.
