Diastereoselectivity in control: The synthetic utility of the CH functionalization/Cope rearrangement reaction has been greatly expanded by the design of substrates that will react through a boat transition state instead of a chair transition state. The products are formed with the opposite diastereoselectivity as previously obtained (see scheme, ABSA= acetamidobenzenesulfonylazide).
控制中的非对映选择性:通过底物的设计, CH官能化/Cope重排反应的合成效用得到了极大的扩展,底物将通过船过渡态而不是椅过渡态进行反应。形成的产物具有与之前获得的相反的非对映选择性(参见方案,A
BSA=乙酰
氨基苯磺酰
叠氮)。
