(5R)-5-Phenyl[1,3,4]oxadiazinan-2-one (6) is an easily available building block and acts as a chiral non-racemic precursor for azomethine imines. The ylid can be formed regioselectively with various aldehydes and reacts in an efficient manner with a wide range of dipolarophiles. The regio- and diastereoselectivity of the cycloadditions have been fully investigated and can lead, in the best cases, to the creation of three contiguous asymmetric centers in a single step, with complete control of relative and absolute configurations.
