    摘要: 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 R6 are defined as above, and; A, according to the reprocessing, represents a radical of formula COOH, —C(OH)R5 or —C(O)R5, whereby R5 is defined as above.

    摘要: The present invention relates to a process for the preparation of a 1-methyl-1H-tetrazole-5-thio derivative comprising reaction of a halomethyl substrate with 1-methyl-H-tetrazole-5-thiol to obtain a thio-ether compound, and oxidizing the thio-ether compound to the corresponding sulfone. In case of a chiral halomethyl substrate, the resulting chiral diol sulfone derivative is suitable as a building block for statin type compounds.
