Abstract

Abstract Reduction of 2, 2-diphenyl-1-nitroethylene (1) and 2-(2-pyridyl)-2-phenyl-1- nitroethylene (5) is achieved by using the NADH model in the pyrrolopyridine series 2a to give 2, 2-diphenyl-1-nitroethane (3) and 2-(2-pyridyl)-2-phenyl-1-nitroethane (7) respectively in 40% yield. The asymmetric reduction of 2-(2-pyridyl)-2-phenyl-1-nitroethylene by the chiral NADH model 2b is studied. Thus, 2-(2-pyridyl)-2-phenyl-1-nitroethane (7) is ...
