Synthesis of functionalized biaryl compounds via ring expansion of alkenylcyclobutenones
摘要:
Various functionalized biaryls are accessible via a simple two-step process. Treatment of a] kenylcyclobuten ones with aryllithium provides ring-opened trienes, which are smoothly cycloaromatized under thermal conditions. (C) 2002 Elsevier Science Ltd. All rights reserved.
