photochemical step in the total synthesis of indanorine. The excited-state character of 4,5-dimethoxy-2-methylphenacyl epoxide was changed from an unfavorable 3π,π* state to a productive 3n,π* state by a temporary structural modification, resulting in a relatively efficient and high-yielding formation of an indanone derivative. The corresponding structural modification was selected on the basis of quantum

Novel substituted 6,7-dimethoxy-1-tetralones and 5,6-dimethoxy-1-indanones have been synthesized and evaluated for their cytotoxicity. Compounds with 3'-lipophilic. 3',5'-dilipophilic, or 3',5'-dilipophilic-4'-hydrophilic substituents on (E)-2-benzylidene moiety showed highly cytotoxic effects. The unique structure of 42 possibly matches the pharmacophore features for these cytotoxic compounds. (C) 2000 Elsevier Science Ltd. All rights reserved.
