Abstract

(Chemical Equation Presented) A diastereoselective synthesis of polyoxin analogues termed phosphonoxin B1 and B2 has been achieved. The key step was sulfinimine-mediated asymmetric formation of (RS,2S,3S,4S)-β- aminophosphonate 3a or (S_S,2R,3S,4S)-β-aminophosphonate 7 as the major diastereoisomer. A double stereodifferentiation effect was not observed, and the diastereoselectivity is controlled by the absolute configuration of the sulfinyl group.
