D-erythritol derivatives -versatile C<inf>4</inf> chiral building blocks: Synthesis and applications

Among various synthetically important chiral building blocks, four carbon atom (C4) chiral building blocks bearing double and/or multiple functionalities are especially interesting because of their usefulness in synthesis of chiral pharmaceuticals, chiral agrochemicals, chiral polymers, natural products and chiral monosaccharides. This study reviews synthesis of D-erythritol derivatives as chiral C4 synthetic units and their important applications.
