ortho-Induced transition-metal-free C-arylation cyclization reaction for the synthesis of polysubstituted isocoumarins
摘要:
A new protocol for the synthesis of polysubstituted isocoumarins from 2-iodobenzoic acid and beta-diketone compounds has been developed. The occurrence of C-arylation cyclization reaction in transition-metal-free systems and ortho-induced substrates has been exploited. Reactions using these inexpensive conditions have displayed high functional group tolerance and excellent yields. (c) 2012 Elsevier Ltd. All rights reserved.

A practical Cu-catalyzed cascade cyclization of o-halobenzoate with enaminones to construct isoquinolinone derivatives is described. The process involves a Cu-catalyzed intermolecular CC coupling and intramolecular azacyclization, wherein a wide range of enaminones could be tolerated.
