Efficient synthesis of indenes by FeCl3·6H2O-catalyzed intramolecular Friedel–Crafts reaction of aryl-substituted allylic alcohols
摘要:
An efficient procedure for the synthesis of substituted indenes through the FeCl3 center dot 6H(2)O-catalyzed intramolecular Friedel-Crafts cyclization of aryl-substituted allylic alcohols has been developed. This method features the easily available starting materials, cheap catalyst, simple manipulation, and mild conditions. (C) 2009 Elsevier Ltd. All rights reserved.

bond cleavages of simple allylicalcohols have witnessed tremendous progress in recent years. However, an efficient method for cleaving the C–C bond via β-carbon elimination is still comparatively underexploited. In this study, we demonstrate rhodium(I)-catalyzed deketonative transfer vinylation and transfer dienylation of various tertiary allylicalcohols with ketones via β-vinyl and β-dienyl elimination
