The synthesis of structurally complex and highly strained natural products provides unique challenges and unexpected opportunities for the development of new reactions and strategies. Herein, the synthesis of (+)-[5]-ladderanoic acid is reported. En route to the target, unusual and unexpected strain release driven transformations were uncovered. This occurrence required a drastic revision of the synthetic
结构复杂且高度紧张的天然产物的合成为新反应和策略的开发提供了独特的挑战和意想不到的机会。在此,报道了(+)-[5]-梯烷酸的合成。在到达目标的途中,发现了不寻常和意想不到的应变释放驱动的转化。这一事件需要对合成设计进行彻底修改,最终导致通过烯丙基硼化/Zweifel 烯化序列开发出新型逐步环丁烷组装。
