asymmetric transferhydrogenation of α-substituted acrylic acids under mild conditions and avoided the use of high-pressure hydrogen gas was developed. The products included chiral β-amino acids and α-methyl carboxylic acids such as three nonsteroidal anti-inflammatory profens. Deuterium-labeling experiments and DFT studies pointed to an unconventional protonation of a metalacyclopropane complex formed by
