synthesis of the previously unknown parent ring system was developed. Treatment of 3-hydrazino-1,2,4,5-tetrazine (4) with diethoxymethyl acetate gave the parent ring system. Similar treatment of 3-(3,5-dimethylpyrazol-1-yl)-6-hydrazino-1,2,4,5-tetrazine (2) with one carbon cyclizing reagents gave 3,6-di-substituted derivatives of the 1,2,4-triazolo-1,2,4,5-tetrazine ring system.
开发了以前未知的母环系统的合成。用乙酸二乙氧基甲基酯处理3-肼基-1,2,4,5-四嗪(4),得到母体环系统。用一种碳环化剂类似地处理3-(3,5-二甲基吡唑-1-基)-6-肼基1,2,4,5-四嗪(2)得到1的3,6-二取代衍生物,2,4-三唑-1,2,4,5-四嗪环系统。
