Abstract
2,2-Dimethyl-4-chromanone (la), 2,2,7-trimethyl-4-chromanone (Ib) and 7-methoxy-2,2-dimethyl-4-chromanone (ic) have been reduced by sodium o r lithium in liquid ammonia with the presence or without of proton don or. The bicyclic or phenolic products were obtained. Products with red uced benzene ring only were also observed. The possible mechanisms of reductions are considered.
