Synthetic studies of viridenomycin. Construction of the cyclopentene carboxylic acid part

A highly functionalized cyclopentene carboxylic acid derivative, as an advanced synthetic intermediate of viridenomycin, was synthesized. The synthesis commenced with the previously reported highly functionalized tetrahydrofuran derivative prepared from D-glucose. The stereochemical confirmation of the present final compound was conducted by comparison with a compound synthesized very recently by the Meyers group. (C) 2000 Elsevier Science Ltd.
