A new process for the controlled synthesis of the two diasteromeric forms of triazolyl-O,N-acetals of the formula ##STR1## 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).
一种用于控制合成式的两种对映异构体三唑基-O,N-缩醛的新工艺,其化学式为##STR1##其中R代表可选择取代的苯基,可选择取代的苯氧基,可选择取代的烷氧基,可选择取代的烷氧基,可选择取代的烷硫基,烷基羰基,硝基或卤素,n代表0到5之间的整数,条件是如果n代表2到5之间的整数,则R可以代表相同或不同的基团。新的反式取代环氧烷及其用作化合物(I)合成的中间体。
