Oxazolium salt/azomethine ylide approach to aziridinomitosenes.
An enantioselective synthesis of aziridinomitosenes and analogs thereof was investigated using an intramolecular oxazolium salt/azomethine ylide cycloaddition sequence to construct the indoloquinone tetracyclic core.

Approach to the Homoerythrina Alkaloids Using a Tandem N-Alkylation/Azomethine Ylide Cycloaddition
Synthetic efforts toward the homoerythrina alkaloids 1−3 are described. Two separate model systems guided the pivotal [3 + 2] azomethine ylide cycloaddition cascade to form the A−C rings of these alkaloids.
