Abstract: Oxidation of organic substrates by means of singlet oxygen, in which organic substrates which react with 1O2 are admixed with 10-70% H2O2 in an organic solvent in the presence of a molybdate LDH catalyst modified by ethylene glycol, polyethylene glycol or polyol, and the catalytic decomposition of H2O2 to water and 1O2 is then followed by the oxidation to the corresponding oxidation products, and also modified molybdate LDH catalysts.

Abstract: A process for catalytically oxidizing alkylaromatic compounds of the formula (I) Ar—CH2—R where Ar is an optionally substituted, aromatic or heteroaromatic 5-membered or 6-membered ring or a ring system having up to 20 carbon atoms where Ar may optionally be fused to a C1-C6-alkyl group in which up to 2 carbon atoms may be replaced by a heteroatom, and R is hydrogen, phenyl, benzyl or heteroaryl, where the phenyl, benzyl or heteroaryl radicals may also be joined to Ar by a bridge, or R together with Ar forms an optionally substituted ring system which may contain one or more optionally substituted heteroatoms, to the corresponding aromatic or heteroaromatic carboxylic acids in a solvent with ozone in the presence of a transition metal catalyst and optionally in the presence of an acid at a temperature between ?70° C. and 110° C. to the corresponding carboxylic acid.

Abstract: The invention relates to a process for the preparation of glyceraldehyde acetonide by oxidation of 2,2-dimethyl-1,3-dioxolane-4-methanol by an oxidizing agent, wherein the 2,2-dimethyl-1,3-dioxolane-4-methanol is oxidized by an organic N-chloro compound in the presence of an inert base and TEMPO or a TEMPO-derivative. In one embodiment of the invention enantiomerically enriched glyceraldehyde acetonide is prepared from the corresponding enantiomerically enriched 2,2-dimethyl-1,3-dioxolane-4-methanol. Preferably, the organic N-chloro compount is trichloroisocyanuric acid or dichlorodimethyl hydantoin. Preferably, the inert base is sodium acetate or sodium bicarbonate.

Abstract: The invention relates to an improved method for producing chiral or enantiomer-enriched beta amino acids, -aldehydes, -ketones and gamma-amino alcohols, during which an allyl amine of formula (I), in which: R1 represents an alkyl radical, a cycloalkyl radical, an alkyl radical, a heterocycle radical or a condensed or bridged ring system; R2, R3, R4 and R5, independent of one another, can represent H or an alkyl radical, a cyclo alkyl radical, an aryl radical, a heterocycle radical or a condensed or bridged ring system or radicals R1, R2, R3 and R4, together, form ring systems that can optionally contain one or more heteroatoms, whereby radicals R1, R2, R3, R4 and R5 can be substituted once or a number of times, and; R6 represents H or an N-protective group, is transformed; a) by ozonolysis in a solvent and; b) subsequent decomposition of the peroxide-containing solution by means of an oxidizing agent or reductive reprocessing, into the corresponding amino compound of formula (II), in which R1, R2, R3, R4 and
