Synthesis of Hindered 1-Arylnaphthalene Derivatives via Ring Expansion of Benzocyclobutenones
摘要:
[GRAPHICS]Various 1-aryinaphthalenes, including highly substituted derivatives, are accessible via a simple two-step process. Treatment of alkenylbenzocyclobutenones with aryllithium provides two-carbon expanded dihydronaphthalenes, which are readily dehydrated by MsCl-Et3N or PPTS in MeOH.
