2-cyclohexen-1-one ring are synthesized with good to excellent levels of enantioselectivity. The quaternary stereocenter is created through a new synthetic sequence involving three reactions: the enantioselective Birch reduction-allylation, enol ether hydrolysis, and the Cope rearrangement. To illustrate the ability of the sequence to enantioselectively generate complex structures, a variety of substrates are described
