摘要:
NEW MATERIAL:The compound of formula I ([A] is group of formula II W formula IV; when [A] is group of formula II, C 13 -C 14 -C 15 is group of formula V, and when [A] is group of formula III or formula IV, it is group of formula VI; R is H or 1W12C alkyl; R 1 is single bond or 1W5C alkylene; R 2 is 1W8C alkyl, etc.; the configuration of C 9 -C 10 in group of formula IV is Z, that of C 13 - C 14 in group of formula V is E and those of C 12 -C 13 and C 14 -C 15 are E, Z or EZ; when R 1 is single bond, R 2 is not substituted or unsubstituted phenoxy), its cyclodextrin-clathrate compound, or when R=H, its salt. EXAMPLE: 6-Keto-PGD 1 methyl ester. USE: An antitumor agent. PROCESS: A compound of formula I wherein [A] is group of formula II or formula III can be prepared by hydrolyzing the compound of formula VII (R 3 is 1- ethoxyethyl, etc.; R 4 is lower alkyl) under acidic condition. The product wherein [A] is group of formula II can be converted to anothr compound of formula I wherein [A] is group of formula IV by reacting in an aqueous solution of an acid.
