Several α-amino esters (and their hydrochloride salts) were treated with cyanogenazide at ambient temperature in a mixture of water and acetonitrile to form chiral 5-aminotetrazole derivatives in good yields (47–69 %). The cyanogenazide was prepared from cyanogen bromide and sodium azide. Other functionalized α-amino esters (cysteine, arginine, histidine, and serine) were formed in only trace amounts
几种α-氨基酯(及其盐酸盐)在环境温度下在水和乙腈的混合物中用叠氮化氰处理,以良好的产率(47-69%)形成手性5-氨基四唑衍生物。由溴化氰和叠氮化钠制备叠氮化氰。其他功能化的 α-氨基酯(半胱氨酸、精氨酸、组氨酸和丝氨酸)仅以痕量形成,难以通过柱层析纯化。所有 5-氨基四唑(即 1-8)均通过 IR 光谱、1H、13C 和 15N NMR 光谱以及元素分析进行表征。3-7 的结构是通过单晶 X 射线结构分析获得的。

2-(5-Nitroiminotetrazol-1-yl)acetic acid (4) was synthesized from 100% nitric acid and ethyl 2-(5-aminotetrazol-1-yl)acetate (2), which was easily obtained by reaction of ethyl aminoacetate hydrochloride, sodium hydroxide, and cyanogen azide. Compound 4 was also formed with 100% nitric acid and 2-(5-aminotetrazol-1-yl)acetic acid which was prepared from sodium 5-aminotetrazolate and 2-chloroacetic acid. New energetic materials comprised of nitroiminotetrazolate salts with nitroiminotetrazolate and carboxylate anions have been characterized spectroscopically as well as with single crystal X-ray diffraction and elemental analyses. In addition, the heats of formation (ΔHf), and detonation pressures (P) and velocities (D) were calculated. All compounds were insensitive (>40 J) for impact with BAM Fallhammer.

derivatives with 1,3,4‐oxadiazole moiety and tetrazole ring. The synthesized derivatives of sulfonamides were characterized through Fourier transform infrared, 13C‐APT‐NMR, 1H‐NMR, and high‐resolution liquid chromatography–mass spectrometry. The biological activities of resulting compound were also investigated and observed that the compounds reveal strong antimicrobialactivity over some important bacterial
