Indolizidine and quinolizidine derivatives are readily assembled from l-proline or (±)-pipecolic acid and β-ketoaldehydes via a decarboxylative annulation process. These reactions are promoted by acetic acid and involve azomethine ylides as reactive intermediates.
吲哚里西啶和喹诺里西啶衍生物可通过脱羧环合过程,由 l-脯氨酸或(±)-哌啶酸和β-酮醛轻易地组装而成。这些反应由乙酸促进,并涉及亚甲胺叶立德作为反应中间体。
