• Regiospecific Syntheses of the Monomethylated 3-Phenyldihydro-1,2,4-triazin-6(1H)-ones

  日期：——

  Unambiguous syntheses of four unreported monomethylated derivatives of 3-phenyldihydro-1,2,4-triazin-6(1H)-ones, namely, the 1-methyl (2), 2-methyl (3), 4-methyl (4) and the imidic O-methyl derivative (5), are described. Regioselectivity was achieved for the synthesis of (2) by addition of ethyl glycinate to the 1,3-dipolar nitrile imine derived from N- methylbenzohydrazonoyl bromide hydrobromide (8). The key step for the synthesis of (3) was addition of benzyl 3-methylcarbazate (14) to ethyl N-[ chloro (phenyl) methylene ] glycinate (15b). The 4-methyl compound (4) was prepared by cycloaddition of ethyl N-( thiobenzoyl ) sarcosinate (21) with hydrazine hydrate, and the O-methyl compound (5) was prepared by reaction of sodium methoxide with 6-chloro-3-phenyl-4,5-dihydro-1,2,4-triazine (23).

  给您结果：对未报告的3-苯基二氢-1,2,4-三嗪-6(1H)-酮的四种未报告的单甲基衍生物进行了明确的合成，分别是1-甲基（2）、2-甲基（3）、4-甲基（4）和咪唑酸O-甲基衍生物（5）。通过将乙基甘氨酸酯加入从N-甲基苯甲酰肼溴水合物（8）得到的1,3-二极化腈亚胺，实现了(2)的合成的区域选择性。合成(3)的关键步骤是将苄基-3-甲基咔巴嗪（14）加入乙基N-[氯(苯基)亚甲基]甘氨酸酯（15b）。通过乙基N-(巯基苯甲酰)磺酸酯（21）与水合肼进行环加成制备了4-甲基化合物(4)，而O-甲基化合物(5)是通过钠甲醇与6-氯-3-苯基-4,5-二氢-1,2,4-三嗪（23）反应制备的。
