摘要:A new process for the controlled synthesis of the two diasteromeric forms of triazolyl-O,N-acetals of the formula (I) in which R represents optionally substituted phenyl, optionally substituted phenoxy, optionally substituted alkoxy, optionally substituted alkoxy, optionally substituted alkylthio, alkylcarbonyl, nitro or halogen and n represents an integer from 0 to 5, with the proviso that R can represent identical or different radicals, if n represents an integer from 2 to 5. New trans-substituted oxiranes and their use as intermediates for the synthesis of compounds of the formula (I).
