A novel, general and straightforward Ca(NTf2)2/HFIP-mediated rearrangement of cyclopropyl carbinols for the construction of E-homoallylic triflimides has been developed. In this protocol, Ca(NTf2)2 was used as both the OH activator and the triflimide anion source. This transformation takes place under mild conditions and shows an impressive substrate and functional group tolerance.
已经开发了一种新颖、通用且直接的 Ca(NTf 2 ) 2 /HFIP 介导的环丙醇重排,用于构建E-高烯丙基三氟酰亚胺。在该协议中,Ca(NTf 2 ) 2被用作 OH 活化剂和 triflimide 阴离子源。这种转化发生在温和的条件下,并显示出令人印象深刻的底物和官能团耐受性。
