This invention relates to novel process for the preparation of prostaglandin compounds having formula (K), wherein R is selected from the group consisting of C1-C7 alkyl; C7-C17 aralkyl wherein the aryl group is unsubstituted or substituted with one to three substituents selected from the group consisting of C1-C6 alkyl, halo and CF3; and (CH2)nOR2 wherein n is from 1 to 3 and R2 represents a C6-C10 aryl group which is unsubstituted or substituted with one to three substituents selected from the group consisting of C1-C6 alkyl, halo and CF3; and R1 is selected from OR3 and NHR3 wherein R3 is C1-C6 alkyl, H; and dashed lines represents a double bond or a single bond, is disclosed. Novel intermediates are also disclosed.
本发明涉及一种制备公式(K)的前列腺素化合物的新工艺,其中R选自以下组中的一组:C1-C7烷基;C7-C17芳基烷基,其中芳基基团未取代或取代有1-3个取自C1-C6烷基,卤素和CF3的取代基;以及(CH2)nOR2,其中n为1-3,R2代表未取代或取代有1-3个取自C1-C6烷基,卤素和CF3的取代基的C6-C10芳基基团;R1选自OR3和NHR3,其中R3为C1-C6烷基,H;虚线表示双键或单键。本发明还揭示了新的中间体。
