transformed to the 3-hydroxy-8-oxamorphinans 6, a class of potent analgesics and analgesic-antagonists. In ring C of the morphinan nucleus substitution of 8-CH2 with oxygen enhanced both analgesic and antagonist activities, while replacement of hydrogen with a methyl group at C-14 in these compounds enhanced antagonist activity and decreased analgesic activity. Tetrahydrofuranobenzomorphans 3 and 3-hydroxy-8-oxaisomorphinans
由相应的5-烯丙基-9α-羟基-2'-甲氧基-2-甲基-6,7-苯并吗啡喃7制备了3-甲氧基-8-氧吗啡喃9。将先前的化合物转化为3-羟基-8 -oxamorphinans 6,一类有效的镇痛药和镇痛剂。在吗啡核的C环中,用氧取代8-CH2可以增强止痛和拮抗活性,而在这些化合物中C-14处的甲基取代氢则可以增强拮抗活性并降低镇痛活性。四氢呋喃并苯并吗啡喃3和3-羟基-8-氧杂异吗啡喃4表现出较低的活性水平。讨论了拮抗剂活性的结构要求。
