    摘要: The present invention provides an industrially very advantageous process for producing prostaglandins E.sub.1 with fewer steps and in higher yield. The process comprises reacting a 7-hydroxyprostaglandin E with a reactive derivative of an organic sulfonic acid in the presence of a basic compound to form the corresponding 7-organic sulfonyloxyprostaglandin E, treating the resulting 7-organic sulfonyloxyprostaglandin E, after or without isolation, in the presence of a basic compound to form a .DELTA..sup.7 -prostaglandin E, thereafter selectively reducing the carbon-carbon unsaturated bond existing on the .alpha.-chain. Some of the 7-hydroxyprostaglandins E and .DELTA..sup.7 -prostaglandins E used in the process are novel compounds.
