Abstract
| - A PtCl2-catalyzed 3,3-rearrangement/[3+2]-cycloaddition of propargylic 3-indoleacetates is developed. Besides the efficient formation of highly functionalized tetracyclic cyclopentenes, the reaction is dramatically divergent from that catalyzed by cationic AuI. Moreover, the synthetic potential of this method is demonstrated by a succinct synthesis of the tetracyclic core of vindolinine.
