Adducts: Use of Intramolecular Friedel—Crafts Alkenylation
45- 113 Baylis—Hillman
Reaction. — Intramolecular Friedel—Crafts alkenylation of substrates (III) leads to
formation of the corresponding benzocycloheptene derivatives (IV). In analogous reactions of the methyl-substituted derivatives (VI) competitions are observed which
result in mixtures of products (VII)—(X). — (GOWRISANKAR, S.; LEE, K. Y.;
