    Practical Preparation of (Z)-2-(5-Amino-1,2,4-thiadiazol-3-yl)-2-methoxyiminoacetic Acid: A Side-Chain of the Fourth Generation of Cephem Antibiotics
    摘要:
    2-(5-氨基-1,2,4-噻二唑-3-基)-2-(甲氧亚氨基)乙酸的一种Z型异构体(4),是临床上有用的头孢菌素抗生素的共同酰基部分,已通过几个途径的骨架重排从氨基异噁唑制备。3-氨基-5-甲氧基异噁唑(7)与烷氧羰基异硫氰酸酯反应得到甲基2-(5-烷氧羰基氨基-1,2,4-噻二唑-3-基)乙酸酯(8),通过相应的酮酯与O-甲基羟胺的反应转化为目标化合物4。化合物4同样从3-氨基异噁唑(10)制备。此外,2-羟基亚氨基-2-(5-甲氧羰基氨基-1,2,4-噻唑-3-基)乙酸酯(15)在氧化钡和八水合氢氧化钡存在下与甲基碘或硫酸二甲酯的O-甲基化反应仅得到所需的Z型异构体(14a),即甲基2-(5-甲氧羰基氨基-1,2,4-噻二唑-3-yl)-2-(甲氧亚氨基)乙酸酯,进而制得4。

  • Synthesis and evaluation of antiinflammatory activities of a series of corticosteroid 17.alpha.-esters containing a functional group

    contain a functionalized ester group at 17 alpha has been prepared and examined to separate their systemic activity from topical antiinflammatory activity. Introduction of the functionalized ester group at 17 alpha was carried out by an acid-catalyzed formation of cyclic ortho esters with 17 alpha,21-hydroxyl groups of corticosteroids and subsequent acid-catalyzed hydrolysis. As for the functional group
    已经制备并检查了一系列在17α处含有官能化酯基的21-脱氧21-氯皮质类固醇,并将其全身活性与局部抗炎活性分开。通过酸催化形成具有皮质类固醇的17α,21-羟基的环状原酸酯,并随后进行酸催化的水解,来引入在17α的官能化酯基。至于官能团,在17个α-链烷酸酯基的末端碳原子上引入了氯,甲氧基,乙酰氧基,氰基,环丙基或烷氧羰基。检查了这些化合物的局部抗炎活性和全身活性,发现它们显着依赖于17种α-酯的功能。在这些衍生品中,一系列17种α-(烷氧基羰基)链烷酸酯(17α-OCO(CH2)nCOOR)表现出出色的全身活性与局部活性的分离。还研究了亚甲基数(n)和酯的烷基(R)对皮质类固醇衍生物的局部或全身活性的影响。
