Aryl-radical cyclization onto an enamide double bond. A route to benz[d]indeno[1,2-b]azepines
Fidalgo,Castedo,Dominguez
, p. 7317 - 7318 (2007/10/02)
A novel synthesis of benz[d]indeno[1,2-b]azepines from bromoaryl enamides 1a-d has been achieved by way of a regioselective 7-endo-trig radical cyclization with tri-n-butylin hydride.
