A short synthesis of hydroxyalkyl dihydropyrroles has been developed that involves the coupling of propargylamines with α-chloroaldehydes, followed by Lindlar reduction and a one-pot epoxide formation/opening sequence. The application of this process to the synthesis of unnatural iminosugars and a formal synthesis of (−)-swainsonine is described.
已经开发了羟烷基二氢吡咯的简短合成方法,该方法涉及将炔丙基胺与α-氯醛偶联,然后进行Lindlar还原和一锅法环氧形成/打开顺序。描述了该方法在非天然亚氨基糖合成和(-)-swainsonine形式合成中的应用。
