asymmetric synthesis of a glucokinase activator via protonation of the enolate generated from an alkylaryl ketene and (R)-pantolactone. Additionally, a one-pot hydrolysis/oxidation protocol with lithium hydroperoxide was developed to afford a chiral sulfone acid without degradation of the labile stereocenter.

This article describes the development and optimization of chemical reactions and subsequent multi-kilogram preparation of the glucokinase activator (R)-1 to fund clinical evaluation as a potential therapeutic for type II diabetes. The major process developments presented here are a Wittig olefination isomerization based synthesis of an E-acrylic acid, an optimized enantioselective hydrogenation of the E-acrylic acid, and a challenging final amide coupling.
