The synthetic versatility of oxazolidinethiones

Abstract

Different methods for the preparation of oxazolidinethiones and their more recent applications are reviewed. In this review, novel rearrangements and new reactions have also been summarized which for their homologous oxazolidinones have not been observed. The principal application of oxazolidinethiones has been as chiral auxiliaries in asymmetric aldol addition reactions for the obtention of chiral fragments containing one or two stereogenic centres with the stereochemistry required for the preparation of complex natural products.

Keywords:

• Oxazolidinethiones
• Chiral auxiliary
• Applications
• Asymmetric synthesis
