The total synthesis of dictyodendrins A–F was achieved by using the gold(I)‐catalyzed annulation of a conjugated diyne with N‐Boc‐pyrrole for direct construction of the pyrrolo[2,3‐c]carbazole scaffold. Late‐stage functionalization of the resulting pyrrolo[2,3‐c]carbazole to introduce various substituents provided divergent access to dictyodendrins. Some dictyodendrin analogues exhibited inhibitory
dictyodendrins A-F的总合成是通过金(I)催化的共轭二炔与N -Boc-吡咯的环化反应直接构建吡咯并[2,3- c ]咔唑支架而实现的。所得吡咯并[2,3– c ]咔唑的后期官能化引入各种取代基提供了对十二碳四烯联苯醚的不同途径。一些双齿豆蔻甙类似物对CDK2 / CycA2和GSK3表现出抑制活性。
