epoxy 5-phenylmorphans is being explored in order to determine the conformational requirements of the phenolic ring in a phenylmorphan molecule that may be needed both for binding to a specific opioid receptor and for exhibiting opioid agonist or antagonist activity. Of the twelve possible ortho- and para-bridged isomers (a–f) (Fig. 1), we now report the synthesis of the para-d isomer, rac-(3R,6aS,11aR)-2-methyl-1
为了确定苯基吗啡酮分子中酚环的构象要求,正在探索一系列环氧5-苯基吗啡啉的合成,这可能是结合特定的阿片受体并表现出阿片激动剂或拮抗剂活性所必需的。在十二种可能的邻-和对-桥联异构体(a-f)(图1)中,我们现在报告对-d异构体rac-(3 R,6a S,11a R)-2-甲基的合成-1,3,4,5,6,11a-六氢-2 H -3,6a-甲基苯并呋喃[2,3 - c ]偶氮素-8-ol(3)。化合物3通过5-苯基氮杂双环[3.3.1]非-3-烯骨架的构建(方案1)和随后的环氧桥的闭合(方案2)来合成α-己内酰胺。通过X射线衍射研究确定,环氧桥限制了苯环的旋转,固定了通过苯环的最小二乘平面与原子N(2),C(3),C(11a)之间的二面角),哌啶环的C(6a)(图2)在43.0°,扭转角C(12)C(6a)C(6b)C(10a)在-95.0°。
