Intramolecular Pd-catalyzed C–H functionalization: construction of fused tetracyclic bis-indole alkaloid analogues
摘要:
An efficient Pd-catalyzed intramolecular indole-C2-arylation protocol for the synthesis of pharmaceutically active bis-indole alkaloid analogues from simple and readily available and 3,3'-Bis(1H-indo1-3-y1) methanes derivatives has been developed. The corresponding products could be obtained in moderate to excellent yields, which permits selective modification on either one of the two indole moieties independently. (C) 2013 Elsevier Ltd.

RuCl3·3H2O was found to be an effective catalyst for reactions of indoles, 2-methylthiophene, and 2-methylfuran with aldehydes to afford the corresponding bis(indolyl)methanes, bis(thienyl)methanes, and bis(fur-2-yl)methanes in moderate to excellent yields. Experimental results indicated that mono(indolyl)methanol is not the reaction intermediate under these reaction conditions.
