A convenient, facile, and one-pot methodology for the synthesis of α-carbolines from Baylis–Hillman (BH) acetates, involving three steps (reactions), (1) mono alkylation of 2-nitroarylacetonitriles with BH-acetates, (2) reduction of nitro group into amino group using Fe/AcOH and (3) formation of two (five and six membered) rings, is presented. This methodology is successfully applied to the synthesis
一种方便,便捷,一锅法的由Baylis-Hillman(BH)乙酸酯合成α-咔啉的方法,涉及三个步骤(反应),(1)2-硝基芳基乙腈与BH-乙酸酯单烷基化,(2)提出了使用Fe / AcOH将硝基还原为氨基的方法,以及(3)形成两个(五元和六元)环。该方法已成功应用于生物活性生物碱新隐油菜素的合成。
