methods from triazine 1a and various alcohols, ethanethiol, and amines. Lowest unoccupied molecular orbital (LUMO) energy and solubility for these 1,3,5-triazines were determined to assess their potential as azadienes in inverse-electron-demand Diels–Alder reactions (IDA). The thioester 8 showed less LUMO energy and more solubility than triazine 1, suggesting that it may be a better azadiene to study
制备了各种具有吸电子基团的 1,3,5-三嗪,如酯、硫酯和酰胺。这些三嗪是使用酰氯偶联方法由三嗪 1a 和各种醇、乙硫醇和胺合成的。确定了这些 1,3,5-三嗪的最低未占分子轨道 (LUMO) 能量和溶解度,以评估它们在逆电子需求 Diels-Alder 反应 (IDA) 中作为氮杂二烯的潜力。与三嗪 1 相比,硫酯 8 显示出更低的 LUMO 能量和更高的溶解度,这表明它可能是研究三嗪 IDA 反应的更好的氮杂二烯。
