Abstract
The reaction of o-(allyloxy)bromobenzenes with copper(I) diethyl malonate afforded diethyl o-(allyloxy)phenylmalonates which under the reaction conditions cyclized to give 4,4-bis(ethoxycarbonyl)-3-methylchromans, 4,4-bis(ethoxycarbonyl)-3-methylenechromans, and 3-(3-butenyl)-4,4-bis(ethoxycarbonyl)chromans.
