摘要：

1-Alkenylbenzocyclobuten-1-ols, prepared from benzocyclobutenones via the addition of alkenylmagnesium bromides, or the addition of alkynyllithium reagents followed by (E)-selective reduction of the triple bond, undergo successive thermal 4-pi and 6-pi electrocyclic reactions leading to substituted 3,4-dihydro-1(2H)-naphthalenones.
