Process for the preparation of E-prostaglandins |
| abstract |
Object: To produce E-prostaglandins in a high yield and in a short time with suppressed formation of isomers. n Structure: A process for preparing E-prostaglandins represented by the formula: ##STR1## (wherein A, R 6 and R 7 represent respectively an arbitrary group which does not participate in the reaction; B represents a vinylene or ethynylene group; and R 4 and R 5 may be the same or different from each other and each represents a hydrogen atom or a protective group of the hydroxyl group) which comprises reacting allyl esters of E-prostaglandins represented by the formula: ##STR2## (wherein R 1 and R 2 may be the same or different from each other and each represents a hydrogen atom or a lower alkyl group; R 3 represents a hydrogen atom, a lower alkyl group, an alkenyl group or an aryl group; and A, B, R 4 , R 5 , R 6 and R 7 are as defined above) with at least one substance selected from the group consisting of bases and formic acid in the presence of a zero- or divalent palladium complex or a salt thereof. |
