A new entry towards the synthesis of 1-substituted 3-azetidinones
The synthesis of 1-substituted 3-azetidinones, starting from readily accessible N-(alkylidene)- or N-(arylidene)-2,2,3-tribromopropylamines, is disclosed.

Novel Syntheses of 1,3,3-Trinitroazetidine
Alternative methods for the synthesis of 1,3,3-trinitroazetidine (TNAZ) from epichlorohydrin, and benzhydrylamine have been developed.These approaches employ N-sulfonyl-3-(hydroxyimino)azetidines as penultimate intermediates and represent an improvement over previously published methods which require either diazo containing intermediates or involve low yielding procedures.Parallel methods employing N-benzhydryl- and N-benzyl-3-(hydroxyimino)azetidine were also investigated as alternate routes to TNAZ
