| abstract |
Analogues of 5,6-dihydroprostacyclin of the formula in which the substituents are defined in claim 1, are prepared. These compounds are obtained by halogenating and cyclising a compound of the formula and subsequently reductively dehalogenating the reaction product, with the formation of the desired ether, or by converting the said compound LXII into a corresponding mercury compound and then subjecting the reaction product to the removal of mercury by reduction. The compounds which are obtained may be used for the same pharmacological purposes as the known prostaglandins. |
