Pyrrolidines via cycloaddition reactions

Dipolar cycloaddition reactions are interesting processes for the preparation of several heterocyclic systems due to the generally mild reaction conditions and the simultaneous formation of several bonds in a single operation. The preparation of pyrrolidines via cycloaddition reactions of azomethine ylides is a well known process and has been extensively studied. A strategy based on the reaction of azomethine ylides with a,P-unsaturated ketones was selected by Hollinshead...
