Abstract
The first asymmetric synthesis of optically pure (+) and (-)-Isokotani n A is described. The key steps involve the asymmetric Ullmann couplin g and selective demethylation. The absolute configuration of the natur ally occurring (+)-Isokotanin A is assigned as aR. (C) 1996 Elsevier S cience Ltd
