Excellent enantioselectivities (up to 97 % ee) and diastereoselectivities (up to >99:1 d.r.) have been achieved in the desymmetrization of cyclopentenes by catalytic hydroformylation. This novel methodology provides an efficient and concise synthetic route to chiral cyclopentane carboxaldehydes. The key intermediate, (1S,3S)‐(3‐hydroxymethyl)cyclopentanol, for the synthesis of carbocyclic‐ddA was obtained
在通过催化加氢甲酰化进行环戊烯的不对称化反应中,已实现了出色的对映选择性(高达97%ee)和非对映选择性(高达> 99:1 dr)。这种新颖的方法为手性环戊烷羧酸醛的合成提供了一种有效而简洁的方法。通过三个步骤获得了用于合成碳环-ddA的关键中间体(1 S,3 S)-(3-羟甲基)环戊醇。
