The first practical asymmetric version of the intermolecular Pauson-Khand reaction has been developed based on novel chiral (non-racemic) alkoxy acetylene dicobalt hexacarbonyl complexes. The major adduct from (1R, 2S)-2-phenylcyclohexyloxyethyne and norbornadiene, isolated in 58% yield, is shown to be useful for obtaining chiral 4-substituted 2-cyclopentenones.
基于新颖的手性(非外消旋)烷氧基乙炔二钴六羰基配合物,开发了分子间Pauson-Khand反应的第一个实用的不对称形式。从(1R,2S)-2-苯基环己基氧基乙炔和降冰片二烯中分离出的主要加合物以58%的收率显示,可用于获得手性的4-取代的2-环戊烯酮。
