Compound (+/-)-2d represents an oxide-bridged derivative of the potent 5-(m-hydroxyphenyl)morphan class of opioid analgesics 1. Unlike the 5-(m-hydroxyphenyl)morphans that have a freely rotating phenyl group, 2d has the phenyl ring conformationally restricted at an angle of 49 degrees relative to atoms 1, 3, 11a, and 12 of 2d. The low binding of (+/-)-2d to rat brain homogenate receptor preparations
外消旋(3 alpha,6a alpha,11a beta)-1,3,4,5,6,11a-六氢-2-甲基-2H-3,6a-甲基苯并呋喃[2,3-c]偶氮星-10的合成描述了-ol(2d)。该路线使用烯胺5的酸催化的闭环反应生成不饱和苯基吗啉6。6转化为氧化物桥连的2d是通过引入溴原子的多步方式完成的,然后对酚基甲基进行O-去甲基化醚和碱催化的分子内酚盐置换溴。化合物(+/-)-2d代表有效的5-(m-羟苯基)吗啡类阿片类镇痛药1的氧化物桥连衍生物。与具有自由旋转的苯基的5-(m-羟苯基)吗啡烷不同,2d具有相对于2d的原子1、3、11a和12成49度角限制的苯环构象。
