Assymetric synthesis process

A novel process for the asymmetric hydrogenation of compounds of the formula: II wherein R represent aryl or heteroaryl, to compounds of the formula: I wherein R has the above significance, is carried out using rhodium-diphosphine complexes. A novel process for the asymmetric hydrogenation of compou...
