are iterative use of a phosphate tether-mediated one-pot sequential RCM/CM/H2 with subsequent utilization of either a regio-/diasteroselective cuprate addition or a Pd-catalyzed reductive allylic transposition. This method highlights the asymmetric synthesis of 12 complex polyol subunits in 4–6 one-pot sequential operations with a total of 12–14 reactions, of which 4–5 are catalytic, with minimal workup
报道了一种生产先进多元醇亚基的经济方法。所涉及的关键反应是迭代使用磷酸系链介导的一锅连续RCM/CM/H 2以及随后使用区域/非对映选择性铜酸盐添加或Pd催化的还原烯丙基转座。该方法强调了 12 个复杂多元醇亚基的不对称合成,需要 4-6 个一锅连续操作,总共 12-14 个反应,其中 4-5 个是催化反应,只需最少的后处理和纯化程序。
