cyclization of aci (alkylideneazinic acid) forms of nitrovinylindoles acting as heterotrienes. Subsequent one-pot reduction allowed for efficient access to β-carbolines, including several natural products, alkaloids norharmane, harmane and eudistomin N.
开发了不寻常的级联转化,涉及作为杂三烯的硝基乙烯基吲哚的酸性(亚烷基肼酸)形式的微波辅助电环化。随后的一锅法减少允许有效获取β-咔啉,包括几种天然产物、生物碱norharmane、harmane和eudistomin N。
