[摘要]：A review. Going full circle: Pericyclic reactions can be catalyzed by groups that can bind selectively to a pericyclic transition-state structure (blue) either by interacting directly with rearranging electrons (green) or interacting with substituents (red). The recent success in accelerating six-electron electrocyclizations by using Lewis acids (LAs) is discussed in this Highlight. Future prospects for catalyst design are also emphasized. |
