Abstract

From enantiomerically pure, planar chiral [2.2]paracyclophane amines a series of nitrogen acyclic carbenegold(I) complexes and nitrogen heterocyclic carbenegold(I) complexes are prepared by a modular template synthesis using isonitriles and amines. These chiral catalysts are tested in two reactions, the enantiotopos-selective furanyne cyclization and the enantioselective enyne cyclization. While excellent conversions could be achieved with these new catalysts, the enantioselectivities in only some cases are in the range of best known catalysts for these conversion.
