Systematic SAR optimization of the GPR119 agonist lead 1, derived from an internal HTS campaign, led to compound 29. Compound 29 displays significantly improved in vitro activity and oral exposure, leading to GLP1 elevation in acutely dosed mice and reduced glucose excursion in an OGTT study in rats at doses >= 10 mg/kg.

The scope and mechanism of enantioselective hydride transfer from NADHmodel 4 to prochiral CO and CN compounds were investigated. Efficient chirality transfer from 4 to α-keto esters and α-methoxycarbonylimino esters was achieved. The resemblance in reactivity and stereochemistry of the prochiral CO and CN-CO2Me functionalities in the hydride transfer reaction is attributed to the intervention
