3R-Substituted and Norbornane-Annelated 1<i>H</i>-Phospholanoxides: Synthesis and Structure

Abstract

A method for the synthesis of 3R-substituted and norbornane-annelated 1H-phospholan oxides has been developed. The method is based on the in situ substitution of the Al atom by the P atom in five-membered cyclic alumolanes using phosphorus trichloride. Substituted alumolanes were prepared by the reaction of cycloalumination of aliphatic and aromatic α-olefins and norbornene derivatives with triethylaluminum in the presence of bis(cyclopentadienyl)zirconium(IV) dichloride catalyst.
