资源简介:
Vinyl ethers selectively undergo the combined C–H functionalization/Cope rearrangement reaction via an s-cis/boat transition state. With chiral dirhodium catalysts, products are generated in a highly diastereoselective and enantioselective fashion. This reaction can be considered as a surrogate to the traditional vinylogous Mukaiyama aldol reaction. Effective kinetic resolution has been achieved, leading to the recovery of a cyclic vinyl ether with axial chirality of high enantiomeric purity.
