用钠对二苯并氮杂茂碱(1)进行Birch还原,以良好的产率产生所需的二烯(2)。将二烯(2)与10%硫酸一起加热并容易地环化以提供刺桐碱(3)作为唯一产物,其随后通过用过量重氮甲烷处理转化为已知碱顺式-15,16-二甲氧基刺桐烷-3-酮(4)。
Birch reduction of a dibenzazonine base (1) with sodium produced the desired diene (2) in a good yield. The diene (2) was heated with 10% sulfuric acid and cyclized readily to provide the erythrina base (3) as a sole product, which was subsequently converted by treatment with excess diazomethane to the known base, cis-15, 16-dimethoxyerythrinan-3-one (4).
