摘要
The first examples of azomethine ylides derived from allylic amine and glyoxal precursors are reported. The condensation of primary allylic and alpha-aryl amines with glyoxylates or alpha-aryl glyoxals affords conjugated azomethine ylides that undergo facile [3 + 2] cycloadditon, providing 5-alkenyl pyrrolidine cycloadducts that cannot be accessed through the classical use of amino esters as ylide precursors.
