A previously described neighboring group reaction has been extended to the synthesis of hydroxy-substituted bridged 1,4-benzoxazocines (i.e., 7, 8) bearing a structural analogy to potent analgetics of the hydroxy-6,7-benzomorphan series. In contrast to the latter, the presence of a hydroxyl group in the aromatic ring of the present series destroys all analgesic activity possessed by the unsubstituted
先前描述的邻基反应一直延伸到的羟基取代的合成桥接1,4- benzoxazocines(即,7,8)的轴承的结构类似于所述羟基-6,7-苯并吗啡烷系列的强效镇痛药。与后者相反,本系列芳环中羟基的存在破坏了未被取代的系统所具有的所有止痛活性。
