摘要
Tricarbonyl iron complexes of 1,1,3 and 1,1,2,3-substituted 1,3-dienes are decomplexed under mild conditions by aluminium halides to conjugated cyclopentenones. This is illustrated for the cyclic substitution patterns A and C, leading to spirocyclic and cyclocondensed cyclopentenones. Optically active compounds are obtained in high optical purity from complexed optically active ligands, the cyclocarbonylation reaction being stereospecific.
