The intramolecular 1,3-dipolar cycloaddition reactions of chiral morpholinone-derived azomethine ylides with tethered alkenes and alkynes have been investigated by semi-empirical methods and ab initio quantum mechanics. The observed ecient direction of the asymmetric induction in the 1,3-dipolar cyc
