, p. 1069 - 1079 (2007/10/03)
2,2-Dimethyl-4-chromanone (1a), 2,2,7-trimethyl-4-chromanone (1b) and 7-methoxy-2,2-dimethyl-4-chromanone (1c) have been reduced by sodium or lithium in liquid ammonia with the presence or without of proton donor. The bicyclic or phenolic products were obtained. Products with reduced benzene ring only were also observed. The possible mechanisms of reductions are considered.
Electrochemical synthesis of chroman and euglobal skeletons via cycloaddition reaction of o-quinone methides and alkenes
Chiba, Kazuhiro,Sonoyama, Junko,Tada, Masahiro
, p. 1435 - 1443 (2007/10/03)
Euglobal skeletons were synthesized by the intermolecular cycloaddition reaction of terpenes and o-quinone methides generated in situ by electrochemical oxidation. In a two-phase reaction medium composed of hexane-lithium perchlorate/nitromethane, 2-[1-(p
