Author(s): Sandeep V.Shinde, Wamanrao N.Jadhav, Rajendra P.Pawar, Rajesh H.Tale, Nilesh P.TaleAn efficient and convenient approach to the synthesis of 3,3,6,6-tetramethyl-9-aryl-1,8-dioxo-octahydroxanthene derivatives using inexpensive boric acid as the catalyst (10 mol%) is described. The use of water as reactionmedium is the most important feature of this reaction.
