A series of 4-hydroxycoumarin derivatives was prepared and evaluated for antitumor activity against five human tumor cell lines. A series of 4-hydroxycoumarin derivatives was prepared and evaluated for antitumor activity. The key fragments were 2a-c, 5c, 12b, 13b, 17, and 18 which were prepared via dianion ring cyclization, Friedel-Crafts acylation, and Reformatsky reaction. Compound 20b showed the most potent antitumor activity among the total 12 derivatives and compounds 19a and 19b exhibited efficacy comparable to etoposide in vitro antitumor activity.

A new process for the preparation of a 3-(4'-bromobiphenyl-4-yl)tetralin-1-one known as a key intermediate for the production of rodenticides and clinical medicines is provided. The title compound is prepared from P-bromobiphenylbenzylketone in three steps, wherein one of key inventions is dehydroxylation of 3-(4'-bromobiphenyl)-3-hydroxy-4-phenylbutyric acid ethyl ester using trialkylsilane in trifluoroacetic acid. This new process offers a high yield with a facile way and is more suitable for a commercial production than the prior art methods.
