Chemistry of Four-Membered Cyclic Nitrones. 5. Synthesis and Oxidation of 1-Hydroxyazetidines

1-(Benzyloxy)azetidines 9 are prepared by reductive cyclization of the corresponding O-benzyl oximes (6) that have a leaving group at the β-position.Reduction of the unprotected oxime 6a with sodium cyanoborohydride in acetic acid affords 3,4,4-trimethyli

SYNTHESIS OF 1-HYDROXYAZETIDINES AND THEIR CONVERSION INTO 1,4-DIACETOXY-2-AZETIDINONES

1-Hydroxyazetidines (5), prepared by reductive cyclization of O-benzyl-β-tosyloxy oximes 1 and subsequent debenzylation, can be oxidized selectively either to four-membered cyclic nitrones (6 and 7) or to 1,4-diacetoxy-2-azetidinones (9).
