Abstract
Process for the preparation of L-erythro-5-amino-6-phenyl-dioxanes-1,3, characterized in that L-threo-5-amino-6-phenyl-dioxanes-1,3 of the formula ** (See formula) ** in which R1 and R2 represent hydrogen or alkyl, aryl, aralkyl, hydroaromatic or heterocyclic radicals (optionally substituted), (which may also together form a ring) and are the same or different, or the corresponding L-5-oximino-6-phenyl-dioxanes-1,3 are oxidized in the 5-nitro-combinations and these are reduced in the 5-amino-combinations.
