Abstract: The invention provides 3-(2-formyl-3-hydroxy-5-oxocyclopent-1-enyl)-p ropanoic acid and derivatives thereof having anti-thrombotic activity coupled with low toxicity. Also provided is a method for preparing such compounds by subjecting a 3-[3-hydroxy-5-oxo-2-(.beta.-styryl)cyclopent-1-enyl]-propanoic acid or derivative thereof to oxidative cleavage.

Abstract: A compound of the formula ##STR1## and pharmaceutically acceptable acid addition salts thereof, in which formula the group R.sup.o is trifluoromethyl.Pharmaceutical compositions containing these compounds are useful for treatment of depressive disorders.

Abstract: 3.alpha.-Hydroxy and 3.alpha.-acyloxy- .DELTA..sup.9(11) -5.alpha.-D-homo-20-ketopregnenes of the formula ##STR1## wherein R is hydrogen or acyl, R.sub.1 is hydrogen or methyl and R.sub.2 is methyl or ethyl, are produced by esterifying a corresponding 3.beta.-hydroxy-5.alpha.-20-keto pregnane of the formula ##STR2## wherein R.sub.1 and R.sub.2 have the values given above, with m-iodo-benzoic acid with inversion of the 3.beta.-oxy group to a 3.alpha.-oxy group; chlorinating the thus-produced 3.alpha.-m-iodobenzoyl ester with dichloroiodobenzene under irradiation; and treating the reaction product with a dehydrohalogenating silver salt. Optionally thereafter, the 3.alpha.-iodobenzoyl group is split off in a conventional manner to produce the corresponding 3.alpha.-hydroxy steroid and optionally the thus-produced 3.alpha.-hydroxy steroid is esterified to produce a desired 3-ester thereof.
