    摘要: Novel N-acyl depeptides of the formula:R.sup.2 --NH--CHR.sup.1 --CO--ASin which AS, R.sup.1 and R.sup.2 have certain, more precisely defined meanings. These N-acyl dipeptides are more stable under conditions of sterilization (121.degree. C.) than corresponding, non-acylated dipeptides. On the other hand, they are cleaved more rapidly and more completely at the peptide bond in the living organism than the cleavage of the acyl group from simple N-acyl amino acids takes place. They can therefore be used with advantage as a source for the carbon terminal amino acid in mixtures and solutions for artificial nutrition or in culture media for cell cultures.

    摘要: The known nuclear hydroxylation of phenol or substituted phenols or phenol ethers with organic solutions of hydrogen peroxide in the presence of a catalyst is carried out in improved manner by employing both (1) a special, practically water free solution of hydrogen peroxide in an organic solvent which forms an azeotrope with water, which azeotrope boils below the boiling point of hydrogen peroxide, and (2) selenium dioxide as a catalyst. Through this, the nuclear hydroxylation is substantially simpler than previously. Besides, for the first time, it is possible to control the ortho to para ratio or the two ortho ratios to each other.

    摘要: 1,2-Diols of the formula: ##STR1## where R.sub.1 and R.sub.2 are hydrogen, alkyl of 1 to 10 carbon atoms or such as alkyl substituted by a halogen, a hydroxy group, a phenyl group, a methoxy group, or an ethoxy group, a phenyl group or a furyl group or R.sub.1 and R.sub.2 together form an alkylene group of 2 to 7 carbon atoms are formed by hydrogenating a correspondingly substituted cyanohydrin in an aqueous medium first in the presence of a hydrogenation catalyst and an acid at a temperature between -20.degree. and +25.degree. C. and a hydrogen pressure of less than 10 bar until per mole of cyanohydrin employed there is taken up one mole of hydrogen and then the hydrogenation continued to the end of the absorption of hydrogen in the presence of metallic nickel at a temperature between 30.degree. and 100.degree. C. and a hydrogen pressure between 10 and 150 bar.
