Rhodium-catalyzed asymmetric anti-Markovnikov hydroformylation of α-substituted acrylates/acrylamides has been developed. By employing the Rh/(S,S)-DTBM-YanPhos complex, a series of β-chiral linear aldehydes were obtained in high yields (up to 94% yield) and high enantioselectivities (up to 96% ee). The utility of this methodology is demonstrated by a gram-scale reaction and a concise synthetic route to chiral ?3-butyrolactone.
Stereochemistry in enzyme inhibition: Synthesis and evaluation of enantiomerically pure 2-benzyl-3-formylpropanoic acids as inhibitors of carboxypeptidase A

Both enantiomers of 2-benzyl-3-formylpropanoic acid were synthesized in five steps starting with hydrocinnamic acid and each enantiomer assayed for inhibitory activity against carboxypeptidase A to find that the (R)-form is 674-fold more potent than its e
