Five types of troponoids including 40 molecules were prepared by means of palladium(0)-catalyzed carbonylation and successive acylation or benzoylation after immobilization of 2-methoxy-5-trifluoromethylsulfonyloxytropone on solid support. Four types of them showed mesophases. The final products have enough purity to detect their mesomorphic properties. (C) 2003 Elsevier Science Ltd. All rights reserved.
