A new, facile preparation of enamines was achieved via a two-step sequence: (i) the ready formation of an N-(α-aminoalkyl)benzotriazole derivative from equimolar amounts of benzotriazole, an aldehyde, and a secondary amine, (ii) the elimination of benzotriazole from the derivative by sodium hydride in tetrahydrofuran (THF). The method provides enamines in good overall yields based on the quantity of
分两步完成新的简便的烯胺制备:(i)由等摩尔量的苯并三唑,醛和仲胺容易地形成N-(α-氨基烷基)苯并三唑衍生物(ii)在四氢呋喃(THF)中用氢化钠消除衍生物中的苯并三唑。该方法基于所用胺的量提供了良好的总收率的烯胺。
