摘要

1-Alkenylbenzocyclobutenols, prepared from benzocyclobutenones via the addition of alkenyl Grignard reagents or the addition of alkynyllithium reagents followed by (E)-selective reduction, undergo successive thermal 4π and 6π electrocyclisations to give substituted 3, 4- dihydro-1 (2H)-naphthalenones. An analogous sequence gave 3, 4,-dihydro-1 (2H)- anthracenone from naphtho [b] cyclobuten-1 (2H)-one.
