be extended to the morphine core structure, we have made five novel 3-amino-3-desoxymorphine derivatives of general structure 5 where RR'N = H(2)N, CH(3)NH, (CH(3))(2)N, C(6)H(5)NH, and C(6)H(5)CH(2)NH. Relative to morphine, these derivatives had 38-273-fold, 11-41-fold, and 10-141-fold lower affinity for mu, delta, and kappa opioid receptors, respectively. Target compounds were made via Pd-catalyzed
作为鉴定新型阿片受体相互作用剂的努力的一部分,我们最近制备了环唑嗪的一系列8-(取代)氨基类似物。我们发现手性8-苯基氨基(NHC(6)H(5))环偶氮衍生物对kappa阿片受体具有亚纳摩尔亲和力,对mu,阿片受体具有较低的2倍亲和力。为了确定(取代)氨基的益处是否可以扩展到吗啡核心结构,我们制备了5个通式5的新颖3-氨基-3-脱氧吗啡衍生物,其中RR'N = H(2)N,CH( 3)NH,(CH(3))(2)N,C(6)H(5)NH和C(6)H(5)CH(2)NH。相对于吗啡,这些衍生物对mu,delta和kappa类阿片受体的亲和力分别低38-273倍,11-41倍和10-141倍。通过Pd催化的吗啡3-三氟甲基磺酸酯底物的氨化制备目标化合物,其中6-OH基团被叔丁基二苯基甲硅烷基保护。为了选择性地制备6-叔丁基二苯基甲硅烷基氧基吗啡,开发了一种新的高产率方法,其中在正常条件下将吗啡双
