the ester functional group to an aldehyde using lithium tri-tert-butoxyaluminum hydride. Especially, this method offers a different perspective for fully substituted 1,2,3-triazoles with high regioselectivity and high yields. The structure of fully substituted triazoles was verified using FTIR, 1H, 13C NMR spectroscopy, HRMS, advanced NMR techniques (COSY, C-APT, HSQC, and HMBC), and X-ray crystallography
开发了一种新的方法,可在温和条件下一步制备 1,4,5-三取代的 1-苄基-5-甲酰基-1,2,3-三唑-4-羧酸酯。该方法包括使用三叔丁氧基氢化铝锂将酯官能团还原为醛。特别是,该方法为完全取代的1,2,3-三唑提供了不同的视角,具有高区域选择性和高产率。使用 FTIR、 1 H、13 C NMR 光谱、HRMS、先进 NMR 技术(COSY、C-APT、HSQC 和 HMBC)和 X 射线晶体学验证了完全取代的三唑的结构。
