Synthesis of 5,6-indolo-12-crown-4 ethers

Abstract

o-Alkyl derivatives of N-acetylaminobenzo-12-crowns-4 4a-f were prepared by Pd-Cu-catalyzed alkynylation of 5′-N-acetylamino-4′ -iodobenzo-12-crown-4 (2). Cyclization of compounds 4a-f afforded the corresponding substituted 5,6-indolo-12-crowns-4 5a-c.
