base-promoted tandem condensation N-alkylation reaction for the formation of trisubstituted hydrazones has been developed employing aldehydes and hydrazines with alkyl halides. Crucially, this reaction successfully overcomes chemoselectivity problems, allowing for the reaction of multiple components in a one-pot manner. Halo- and heterofunctional groups, as well as free hydroxyl and amino groups, are tolerated
使用醛和肼与烷基卤,开发了一种实用的碱促进串联缩合N-烷基化反应,用于形成三取代腙。至关重要的是,该反应成功地克服了化学选择性问题,允许多种组分以一锅的方式进行反应。在该转化中可以耐受卤代和杂官能团以及游离羟基和氨基,从而以良好到优异的收率产生各种三取代腙。
