✦ Synopsis

The reactions of carbodiimides with N-sulfonyl substituted ketenimines and those of bis(imino)thiazetidines with ester phosphoranes yield 2,4-bis(imino)azetidines. The limitations of the methods are outlined. Four-membered ring amidines' (imino analogues of B-lactams), as well as the corresponding imminium salts, 2 and 4-iminoazetidin-2-ones 334 are of current interest. For bis(imino)azetidines

Chiral C 2 -symmetric N-benzylazetidines have been conveniently prepared from optically pure anti-1,3-diols without loss of enantiomeric purity. N-Debenzylation led to the corresponding N-unsubstituted azetidines, which were then subjected to palladium-catalysed coupling reactions with aryl [a]
