摘要

Recently, phosphine-catalyzed [3+2] cycloadditions of allenoates with electron-deficient olefins and irnines-a process which provides efficient access to a variety of synthetically useful carbo-and heterocycles from readily available starting materials-have received considerable research interest since the pioneering works of Lu and co-workers. As a result of continuing efforts from many research groups in this field, an array of new annulation reactions were disclosed, in which a-or γ-substituted allenoates, allylic compounds, and electron-deficient olefins were recognized as novel "three-carbon-atom units" and "two-carbon-atom units".
