[reaction: see text] Two new series of 2,2'-bipyrroles and 2,2'-thienylpyrroles have been prepared by trimethylsilyl trifluoromethanesulfonate (TMSOTf)-mediated reaction of donor-acceptor cyclopropanes with 2-cyanopyrroles and 2-cyanothiophene, respectively. This method opens the door toward a wide variety of unsymmetrical bipyrroles and thienylpyrroles.
[反应:见正文]通过三甲基甲硅烷基三氟甲磺酸酯(TMSOTf)介导的供体-受体环丙烷分别与2-氰基吡咯和2-氰基噻吩反应,制备了两个新的2,2'-联吡咯和2,2'-噻吩基吡咯系列。这种方法为各种不对称的双吡咯和噻吩基吡咯打开了大门。
