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 reduc

Reduction of the piperidine keto esters 16-19 using fermenting bakers' yeast provides high yields of the corresponding hydroxy esters 20, 26, 32 and 37 respectively, exclusively as the cis-diastereoisomers and with good levels (≥80%) of enantiomeric enrichment. The relative stereochemistries of the products were deduced from NMR data while the absolute configurations were determined by degradation to known piperidinemethanol derivatives or, in the case of hydroxy ester 37, by homologation to (R)-3-quinuclidinol 41b.
