Abstract: There are described new squaric acid esters, particularly mono-ortho esters, di-ortho esters, ortho ester anhydrides and ortho ester halides of squaric acid; a new process for producing these squaric acid esters; and a process for converting the squaric acid esters into squaric acid. It is possible by the new process to produce, with the use of readily obtainable starting products, the new squaric acid esters according to the invention in an economical manner and with good to very good yields; and the squaric acid esters can be converted under mild reaction conditions into squaric acid.

Abstract: Caprolactone modified polyesters, derived from an aliphatic diol, an aliphatic dicarboxylic acid or mixtures thereof, optionally with a proportion not exceeding 10 mole % of an aromatic dicarboxylic acid and terminated with an alcohol or monocarboxylic acid are good plasticizers for thermoplastic polymers especially polyvinyl chloride.

Abstract: Caprolactone modified polyesters derived from an aliphatic dihydroxy compound and a mixture of aliphatic dicarboxylic acids and a proportion above 10 mol % of the total acids used, of an aromatic dicarboxylic acid and terminated with an alcohol or monocarboxylic acid such that the molecular weight ranges from 500 to 1400 are good plasticizers for polymers, especially polyvinyl chloride.

Abstract: A-40104 antibiotic complex, comprising active factors A, B, C, and D, produced by submerged aerobic fermentation of Clitopilus pseudo-pinsitus. Individual factors, A, B, and C have been isolated. A-40104 factor C is the known antibiotic pleuromutilin. A-40104 factors A and B are novel antibiotics related to pleuromutilin. A-40104 factor A, the major new factor, is the D-xylose acetal derivative of pleuromutilin. A-40104 factors A and B, their 19,20-dihydro derivatives and the per(C.sub.2 -C.sub.6)alkanoyl derivatives of factors A and B and of their 19,20-dihydro derivatives are active against gram-positive and gram-negative bacteria, anaerobic bacteria, and Mycoplasma.

Abstract: Glycolic acid or the esters thereof are prepared by reacting paraformaldehyde or trioxane or a mixture thereof with formic acid or a formic acid ester in the liquid phase at a temperature of from 70.degree. to 200.degree. C in the presence of a strongly acidic catalyst.

Abstract: The present specification provides novel intermediates and novel processes for the synthesis of various side chain and skeletal analogs of Thromboxane B.sub.2 (11.beta.-homo-11a-oxa-PGF.sub.2.alpha.). These analogs are particularly and especially useful as reproductive cycle control agents.

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.
