Abstract: A method for preparing 16-hydroxy-16-methyl prostaglandin E derivs. of formula (I) comprises (a) reacting a cpd. of formula (II) and a cpd. of formula (III) (wittig reaction); (b) protecting the 16- position OH gp. with tetrahydropyranyl gp. and removing the 9- position trialkylsilyl gp.; and (c) oxidizing it and removing the 1- and 6-position protecting gp. In the formulas, R1= t-butyl dimethyl silyl; R2= t-butyl dimethyl silyl, tetrahydropyran-2-yl or 1-ethoxy-1-ethyl; R3= tetrahydropyran-2-yl or 1-ethoxy-1-ethyl; X= hydroxymethyl or methoxy carbonyl. The cpds. (I) have an antiulcer activity.
Abstract translation: 制备16-羟基-16-甲基前列腺素E衍生物的方法。 式(I)的化合物包括(a)使cpd反应。 的式(II)和cpd。 的式(III)(无反应); (b)保护16位OH gp。 与四氢吡喃基gp。 并除去9-位三烷基甲硅烷基。 和(c)氧化并除去1-和6-位保护gp。 在式中,R1 =叔丁基二甲基甲硅烷基; R2 =叔丁基二甲基甲硅烷基,四氢吡喃-2-基或1-乙氧基-1-乙基; R3 =四氢吡喃-2-基或1-乙氧基-1-乙基; X =羟甲基或甲氧基羰基。 cpds。 (I)具有抗溃疡活性。
