Abstract
The reduction of precocene I (1a), precocene II (1c) and 6-methoxy-2,2 -dimethyl-2H-chromene (1b) with sodium or lithium in liquid ammonia wa s examined. The phenolic compounds and the bicyclic one with partially reduced benzene ring were obtained as the major products from precoce ne I and 1b, respectively. The demethoxylation during the reduction of precocene II was observed.
