Abstract: 3,4-DIHYDRO-1,2,3-OXATHIAZINONES ARE OBTAINED WHEN REACTING KETONES WITH ARYLOXYSULFONYL ISOCYANATES. THE COMPOUNDS HAVING LOW-MOLECULAR SUBSTITUENTS ARE ARTIFICIAL SWEETENING AGENTS AND THE DERIVATIVES HAVING HYDROPHOBIC SUBSTITUENTS ARE INTERFACIAL ACTIVE AGENTS. ALL OF THE NEW COMPOUNDS ARE ORGANIC INTERMEDIATES HAVING A PLURALITY OF REACTIVE GROUPS.

Abstract: New 1-hydroxy-2-pyridones of the general formula
IN WHICH R1 is alkyl of 1 to 17 carbon atoms, cycloalkyl of 5 to 8 carbon atoms, cyclohexylalkyl or phenalkyl both having 1 to 3 carbon atoms in the alkylene chain or Alpha -furyl, all of which may be substituted by halogen and R2 to R4 are hydrogen or lower alkyl or 2 adjacent substituents together form a trimethylene or tetramethylene chain, and in which R1 to R4 together contain at least 2 carbon atoms, are prepared by contacting unsaturated delta -keto esters or mixtures thereof with hydroxylamine and subjecting the products to cyclization. The compounds exhibit antimycotic properties.

Abstract: POLY-B-AMIDES ARE PREPARED IN A TWO-PAHSE DISPERSION BY POLYMERIZING B-LACTAMS WHICH ARE UNSUBSTITUTED AT THE NITROGEN ATOM. ONE OF THE PAHSES CONSISTS OF AN ALIPHATIC OR A CYCLOALIPHATIC HYDROCARBON AND THE OTHER OF A SOLUTION OF THE LACTAM IN A HIGHLY POLAR SOLVENT. THE PREPARATION IS CARRIED OUT IN THE PRESENCE OF CATALYSTS, PROMOTERS AND EMULSIFIERS, THE POLY-B-AMIDES PRODUCED ARE SUITABLE FOR THE MANUFACTURE OF MOLDED ARTICLES, FILMS AND FILAMENTS.

Abstract: Novel substituted 2-pyrones

IN WHICH ONE OF THE RADICALS R1 to R4 is substituted by an acryloyl or methacryloyl group are obtained from the corresponding 2-pyrone derivatives and acrylic or methacrylic acid or a derivative thereof. The compounds can be polymerized forming light-sensitive polymers which are cross-linked by the action of light and may be used in light-sensitive copying layers.
