The diastereoselective reduction of α-benzyl-α-sulfinylketimine 1a with DIBAL–H/ZnCl 2 , LiEt 3 BH, and NaCNBH 3 /AcOH–TFA has been studied. Under the first conditions, the reaction was completely stereoselective and the sulfinyl group involvin

The enantioselective synthesis of (+)-(2S,4S,6S)-1-ethoxycarbonyl-6-hydroxymethyl-4-methylpipecolamide 16 is described. The absolute configuration of stereocenters introduced in (+)-16 was assigned on the basis of 1H NMR data. The results extend the
