A concise synthesis of pyrano[3,2‐e]indole alkaloid fontanesine B by a Fischer indolization is described. This key Fischer indolization starts with the pyran‐ring and alkene intact, facilitating potential synthetic applications. Furthermore, fontanesine B and its isomer were evaluated for in vitro antiproliferative activity against human colorectal cancer cells. The isomer of fontanesine B showed higher
描述了通过Fischer吲哚化反应合成吡喃并[3,2- e ]吲哚生物碱font烷B的方法。费舍尔关键的这种吲哚化反应从完整的吡喃环和烯烃开始,促进了潜在的合成应用。此外,评估了font丹碱B及其异构体对人结肠直肠癌细胞的体外抗增殖活性。ane丹宁B的异构体显示出比天然产物font丹宁B高的抗增殖活性(2)。
