Abstract:

Oxyarylation of olefins has been used by our group to prepare naturally occurring pterocarpans and derivatives. Recently we reported the oxyarylation of dihydronaphthalene and chromenes by oiodophenols under conditions favouring the cationic mechanism, reactions which were analyzed by ESIMS. In this paper we describe the scope of these oxyarylations using electron-rich 2a-c and one electron-poor olefins 3 with ortho-iodophenols and its acetates 1a-h under microwave irradiation.
