摘要

Abstract Novel syntheses of 4, 5-dihydro-1, 2, 4-triazin-6 (1H)-ones were developed by use of imidoyl chlorides. The overall yield of 4, 5-dihydro-1, 2, 4-triazin-6 (1H)-ones prepared from amino acid imidates and hydrazines was improved by the development of a much more efficient synthesis of the imidates. The new 1, 2-, 1, 4-and 5, 5-dimethyl dihydro-1, 2, 4-triazin- 6 (1H)-ones have been synthesized by cyclocondensation/cycloaddition pathways. Base- ...
