Abstract

An efficient two step procedure for the synthesis of 2, 3, 4, 9-tetrahydro-1H-xanthene-1, 9- diones is described. A study of their conjugate additions has shown them to be efficient Michael acceptors. Reaction of 2, 3, 4, 9-tetrahydro-1H-xanthene-1, 9-dione with tris (methylthio) methyllithium, followed by mercury () catalysed
