via Diels–Alder reaction of 3-(tetrazol-5-yl)-nitrosoalkenes is reported. It was also demonstrated that reduction of these adducts followed by deprotection of the tetrazolyl group give 5-(1-aminoalkyl)-1H-tetrazoles, α-amino acid analogues.
据报道,一般通过3-(四唑-5-基)-亚硝基烯烃的狄尔斯-阿尔德反应生成带有1 H-四唑基取代基的1,2-恶嗪和开链肟的一般路线。还证明了这些加合物的还原,然后是四唑基的脱保护,得到了5-(1-氨基烷基)-1 H-四唑,α-氨基酸类似物。
