Objectives To gain knowledge about birch reduction and application in organic synthesis
Backgroundhaving electron-withdrawing substituents such as COOH, COR, and NO2 yield the corresponding1,4-dihydro compounds (3) as shown below (Scheme 1).The methoxycyclohexadienes (2) obtained from the metal-ammonia and alcohol reduction ofanisoles are synthetically useful because of their unique structural features, which comprise (i) the directedenol-ether double bond and (ii) the diene system and its reactions in the form of unconjugated, andconjugated with the effects of alkoxyl group on transformations of products. The reactions of the dienesas unconjugated include the ability to form a regiospecific carbanion formation without the presence ofanion-stabilizing groups such as CO2R and Ph, while the conjugated dienes are useful in the Diels–Alder*Lecture presented at the 4th Florida Heterocyclic Conference, Gainesville, FL, U(2)
Conclusion *we know about birch reduction *we used birch reduction in organ synthesis
