Chiral non racemic carbazate 1, derived from (R)-(-)-phenylglycinol, reacts regioselectively with benzaldehyde or its dimethylacetal to give an azomethine imine. The faci~d, endo/exo and regio selectivities of 1,3-dipolar cycloadditions of this reactive species with various dipolarophiles have been
