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.
