[摘要]：The rapidly expanding field of gold and platinum pi-acid catalysis has led to the discovery of diverse transformations that are initiated with nucleophilic attack onto a metal-activated alkyne. This review brings together those reactions which employ a hetero-atom nucleophile bearing a functional group that can subsequently migrate to effect a formal insertion of the alkyne into a carbon-heteroatom sigma-bond. This reactivity profile is encountered in a range of efficient and powerful cycloisomerisations for the preparation of carbo-and heterocycles. |
