Abstract

Abstract An inexpensive BF 3· Et 2 O-catalyzed annulation reaction of arylacetaldehydes with arylalkynes has been developed. Various substituted phenylacetaldehydes and phenylacetylenes can undergo this reaction, producing corresponding α-aryl substituted naphthalene derivatives. Use of inexpensive and readily available BF 3· Et 2 O catalyst constitutes the most attractive advantage of this transformation.
