adrenergic receptor antagonists, have been prepared by a regioselective oxidation of the corresponding 4-hydroxyphenethylamine derivatives by 2-iodoxybenzoic acid (IBX) in homogeneous as well as in heterogeneous conditions and followed by cleavage of the amino protective group. By using polymer-supported IBX, after the first oxidation, the oxidant can be recovered, regenerated, and efficiently reused for
儿茶酚胺,拟交感神经药和肾上腺素能受体拮抗剂已通过2-碘氧基苯甲酸(IBX)在均相和非均相条件下将相应的4-羟基苯乙胺衍生物进行区域选择性氧化,然后裂解氨基保护基来制备。通过使用聚合物支撑的IBX,在第一次氧化后,氧化剂可以被回收,再生并有效地再使用几次。还已经报道了一种合成许多药物关键成分的N-(甲氧基羰基)多巴胺的有效,简便和绿色的方法。 N-(甲氧羰基)多巴胺-儿茶酚胺-芳族羟基化-2-碘氧基苯甲酸-聚合物负载的IBX
