Reactions of macrocyclic rhodium carbenoids: Regioselective synthesis of indol-3-yl macrocyclic lactones and cryptands

A wide variety of new macrocyclic diazocarbonyl compounds with various spacers was synthesized. Macrocyclic rhodium(H) carberioid insertion with various substituted indoles was performed to afford regioselectively, indol-3-yl macrocyclic di- or tetralactones (C3-alkylation). Double carberioid insertion was also performed to afford indolyl cryptand molecules. (C) 2007 Elsevier Ltd. All rights reserved.
