Abstract

On treatment with Hg(OAc)2 the diene (I), prepared starting from 2-hydroxy-tetrahydropyran, cyclizes regioselectively to give the cyclopentane derivatives (II).

ChemInform Abstract

On treatment with Hg(OAc)2 the diene (I), prepared starting from 2-hydroxy-tetrahydropyran, cyclizes regioselectively to give the cyclopentane derivatives (II). The optically active diene (IV), derived from (+)-camphoric acid, reacts regio- and stereoselectively to afford the ester (V).
