A novel compound selected from the group consisting of 7-(or 6- or 4-) thiaprostaglandin E1 derivatives of the formula
wherein A represents
- in which n is 0,1 or 2, provided that only one A cut of three is (O)n
; R1- R7 and G are defined in claim 1, the 15-epimers of said thiaprostaglandin E1 derivatives, the enatiomers of said thiaprostaglandin E1 derivatives or their 15-epimers, and mixtures of these compounds,
A 7-thiaprostagiandin E, derivatives and/or its optical isomer may be prepared by reacting a 2-organo-2-cyclopentenone (II) with an organic copper-lithium compound (III) to effect conjugation reaction. A 6-thiaprostaglandin E1 derivative and/or its optical isomer may be prepared by subjecting an α-β-unsaturated ketone (IV) and a thiol (V) to the Michael addition reaction. And 4-thiaprostaglandin derivative and/or its optical isomer may also be prepared by the Michael addition reaction from a 2-allyl substituted cyclopentanone (VI) and a thiol (VIII).
Some compounds ((I)-1) amongst the compounds of the formula (I) and/or their optical isomer are useful for controlling vascularactions such as angina pectoris, vasodilation etc.
