Abstract

“Chiral pool” compounds possessing well defined stereocenters and suitable functionality serve as excellent building blocks for the synthesis of natural products and therapeutically important compounds. Tartaric acid is a C2-symmetric molecule available in both enantiomeric forms. It was extensively utilized in the synthesis of privileged chiral ligands/catalysts such as TADDOLs, and as a start point in the synthesis of plethora of compounds. The advent of several new C−C bond forming reactions offers opportunity for the development of novel synthetic strategies based on chiral pool compounds. We found that the desymmetrization of the bis-dimethyl amide/Weinreb amide derived from tartaric acid can be accomplished by controlled addition of Grignard /organolithium reagents leading to the mono keto amides, the reduction of which affords the γ-hydroxy amides. This account describes our research efforts of more than a decade on the synthesis and application of diverse γ-hydroxy amides derived from tartaric acid in the total synthesis of structurally simple to complex bio-active natural products.
