The expedient enantioselective synthesis of 5 bisabolane sesquiterpenes has been achieved using a common, one-pot lithiation-borylation reaction of secondary benzylic carbamates and either protodeboronation or oxidation to give the natural products in fewer than 5 steps, with high yield and >94 : 6 er.
采用一种通用的、一锅法的二级苄基氨基甲酸酯的锂化-硼化反应,实现了 5 种倍半萜类化合物的非对映选择性高效合成,通过脱硼或氧化,可在 5 步以内以高产率 (>94 : 6 er)得到天然产物。
