Asymmetric 1,3-dipolar cycloadditions of cyclic stabilized ylides derived from chiral 1,2-amino alcohols

The use of structurally similar chiral non-racemic azomethine ylides, nitrones and azomethine imines derived from 1,2-aminol alcohols in asymmetric dipolar cycloadditions is reviewed. This general survey underlines the great synthetic potential of dipolar cycloadditions, especially in a diversity-oriented approach and enables a direct comparison of the reactivity of apparently closely related reactive systems.
