2-dicarbofunctionalization of 1,3-dienes employing o-bromoaryl imines as a bis-electrophilic coupling partner. This method provides an entry to prepare disubstituted cis-indanes in high diastereo- and enantioselectivities under mild reaction conditions. The proposed reaction mechanism consists of enantioselective intermolecular migratory insertion and diastereoselective intramolecular allylation as the key
在此,我们报告了钴催化的 1,3-二烯不对称还原 1,2-二碳官能化,使用邻溴芳基亚胺作为双亲电子偶联伙伴。该方法为在温和反应条件下以高非对映选择性和对映选择性制备双取代的顺式茚满提供了一个入口。所提出的反应机制包括对映选择性分子间迁移插入和非对映选择性分子内烯丙基化作为关键的基本步骤。
