摘要:
An efficient regioselective two-step synthesis of alpha-hydroxyenones 3a-p is reported. The methodology involves nucleophilic addition of metalated beta,gamma-unsaturated-alpha-aminonitriles to aldehydes, followed by a mild silver nitrate induced hydrolysis of the aminonitrile adducts to afford the title compounds in overall yields of 61-83%.
