摘要:
Treatment of arylethanals 1 with boron tribromide give 2-phenylnaphthalenes 2 or 1,2,9,10-tetrahydro-1,9-epoxydibenzo[a,e]cyclooctenes 3 by a tandem aldol condensation-intramolecular Friedel;Crafts cyclization or a condensation at the O-position followed by a double Friedel-C:rafts alkylation respectively. In all cases, a total demethylation of the methoxy groups occurs. (C) 1998 Elsevier Science Ltd. All rights reserved.
