Compounds of the general formula I are disclosed as useful intermediates in the preparation of prostanoids:
wherein A represents 0 or H, ORz;
Rz represents hydrogen or a protecting group;
Rx represents hydrogen or a protecting group; and
Ry represents halogen, a substituted thio group, di-substituted amino group, or a group of the formula R2, and R2 represents a straight-or branched-chain alkyl, alkenyl or alkynyl group which may optionally be substituted by one or more carboxyl, carboxylic acid ester, or free or protected hydroxyl, thiol, aldehyde or keto groups; with the provisos that Rx is not hydrogen when A is O and Ry is R2; and that when A is H, ORz RY is R2 and RX and Rz are not both hydrogen.
Processes forthe preparation of these compounds and of 2-substituted 4-hydroxy-cyclopent-2-en-1-one derivatives are also disclosed.
通式 I 的化合物是制备前列腺素的有用中间体:
其中 A 代表 0 或 H、ORz;
Rz 代表氢或保护基团
Rx 代表氢或保护基团;以及
R2 代表直链或支链烷基、烯基或炔基,可任选被一个或多个羧基、羧酸酯或游离或保护羟基、硫醇、醛基或酮基取代;但条件是,当 A 为 O,Ry 为 R2 时,Rx 不是氢;当 A 为 H,ORz RY 为 R2 时,RX 和 Rz 都不是氢。
