A novel protocol to prepare multi-substituted dihydrofuropyridine and dihydropyrrolopyridine derivatives from KOH-catalyzed reactions between readily available N-propargylic β-enaminones and arylaldehydes or N-sulfonyl imines has been developed in moderate to good yields.
已开发出一种新方法，通过在氢氧化钾催化下，使易得的N-炔丙基β-烯胺酮与芳醛或N-磺酰基亚胺反应，制备多取代二氢呋喃并吡啶和二氢吡咯并吡啶衍生物，产率中等至良好。
