1-one to forge the sterically cumbersome bond between the tetrasubstituted and quaternary carbon centers. The present convergent strategy was successfully applied to a seven-step total synthesis of 5-epi-eudesm-4(15)-ene-1β,6β-diol (1).
设计了基于温和自由基的偶联方法用于分子间安装季碳。在室温下用Et 3 B / O 2处理α,α-二烷氧基酰基碲化碲促进了高反应性α,α-二烷氧基碳自由基的形成,该自由基与2-氰基-3-甲基-2-环己烯-1-偶联一个在四取代碳原子和四碳原子中心之间建立空间繁琐的键。本收敛策略已成功应用于5- Epi -eudesm-4(15)-ene-1β,6β-diol(1)的七步全合成。
