Abstract
NEW MATERIAL:A prostacycline derivative shown by the formula I (R1 is alkyl or alkenyl; R2 is alkyl or ethynyl; or both R1 and R2 are H; m is integer of 0W5; n is integer of 0W3; Y is direct bond, trans-vinylene, etc.) its salt, and its alkyl ester.
EXAMPLE: 5,8α-Methylene-10α,14-dihydroxy-14-methylnorprost-4,12(E)-dienoic acid.
USE: A blood platelet coagulation inhibitor. Having almost the same activity as that of PGE1(prostaglandine E1), but stabler than PGE1 and PGI2(prostacycline I2).
PROCESS: A compound shown by the formula II (R1' is alkyl, etc.) is oxidized with DDQ(dichlorodycianobenzoquinone), etc. to give a compound shown by the formula III. COOH or OH group of the compound is protected, if necessary. It is alkylated by a Grignard reagent, or subjected to ethynylation, and, the protecting group is removed, to give the compound shown by the formula I.
