Abstract
The present invention relates to a process for preparation of intermediates (Z,2E)-5-hydroxy-2-methoxyimino-N-methyl-pent-3-enamides from 4-substituted 5-meth-oxyimino-2H-pyran-6-ones and their processing for example to (Z)-5-cyclyloxy-2-[(E)-methoxyimino]-3-methyl-pent-3-enic acid methyl amides. The invention also relates to a process for preparation of 4-substituted 5-imino-2H-pyran-6-ones and to novel intermediates for the preparation of fungicidal (Z)-5-cyclyloxy-2-[(E)-methoxyimino]-3-methyl-pent-3-enic acid methyl amides.
