The convergent total synthesis of furanocembranoids (FC) molestin E, ent-sinulacembranolide A and ent-sinumaximol A was achieved in 20–21 steps in the longest linear sequence (LLS). Building blocks were coupled through a furan metalation sequence and macrocycle formation was effected by Shiina lactonisation. The primary target molestin E was elaborated late-stage to 12 novel FC compounds.
呋喃西松内酯 (FC) 摩尔素 E、 ent -sinulacembranolide A 和ent -sinumaximol A 的收敛全合成在最长线性序列 (LLS) 中通过 20-21 个步骤实现。结构单元通过呋喃金属化序列偶联,大环化合物的形成受到椎名内酯化的影响。主要目标 Molestin E 在后期被精心设计成 12 种新型 FC 化合物。
