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%.

The pracitally unknown α-secondary allylamines 1 have been synthesised in good to very good yields by reaction of allylaminonitriles 7 with Grignard reagents. The reaction is regio- and stereoselective and can also be run with α-aminonitriles 9 and vinyl Grignard reagents.
