compounds has been realized by using a chiral rhodium complex as the catalyst, and the corresponding chiral cyclopropanes could be formed in good yields with high enantioselectivities. Moreover, using acceptor–acceptor dimethyl 2-diazomalonate as the carbene precursor, a novel 1,4-rearrangement of a Boc group from N to C has also been discovered under rhodium catalysis.
以手性铑配合物为催化剂,实现了N-取代的2-吡啶酮与重氮化合物的对映选择性环丙烷化反应,能够以良好的收率和高对映选择性生成相应的手性环丙烷。此外,使用受体-受体 2-重氮丙二酸二甲酯作为卡宾前体,还发现了在铑催化下 Boc 基团从 N 到 C 的新型 1,4-重排。
