Regio- and stereoselective synthesis of key 1-methyl carbapenem intermediates via hydroformylation using a zwitterionic rhodium catalyst

The asymmetric hydroformylation of a 4-vinyl β-lactam catalyzed by a rhodium catalyst with a chiral phosphine ligand was investigated. The catalytic system consisting of a zwitterionic rhodium catalyst, (NBD)Rh+(C6H5B
