标题:可见光诱导能量转移合成多取代 2-氧杂双环 [2.1.1] 己烷
摘要:双环支架的合成引起了越来越多的兴趣,因为它们在现代药物开发中非常重要.在这里,我们报告了一种策略,通过可见光诱导的三重态能量转移催化,从易于获得的苯甲酰甲酸酯和双环 [1.1.0] 丁烷中,在一次操作中获得多取代的 2-氧杂双环 [2.1.1] 己烷.该过程被提议涉及正式的 [2π + 2σ] 光环加成/主链 C-H 抽象/芳基迁移序列.各种各样的(杂)芳基成功地迁移到主链(c2)位置以提供以前无法接近的双环分子,并且产物的酯基可以作为下游操作的手柄,从而提供快速构建分子的机会复杂性和访问新的 Sp 3-丰富的化学空间.
