Abstract
The stereoselective total synthesis of decarestrictine O, a polyketide natural product is described. The synthesis involves MacMillan α-hydroxylation, C1-Wittig olefination, hydrolytic kinetic resolution and ring closing metathesis (RCM) as key steps. Improved efficiency was achieved by using the DIBAL mediated reductive transformation of trans-dimethyl l-tartrate acetonide into ε-hydroxy α,β-unsaturated ester in a single step.
