such as short reaction times, good yields, solvent-free conditions, and easy workup with the green aspects by avoiding toxic catalysts and solvents. The crystal structure of 4b has been determined by X-ray crystallography. This compound crystallizes in the monoclinic space group C2/c with cell parameters a = 21.9285(5) A, b = 10.3221(2) A, c = 18.5979(5) A, β = 108.759(3)°, V = 3985.99(18) A3, Dcalc = 1
α-氨基膦酸酯的三组分合成描述了在无溶剂条件下,醛、2-氨基苯并噻唑和亚磷酸三乙酯在作为催化剂的 InCl3 存在下的反应,以生成特定的 α-氨基膦酸酯。这些产品有两个潜在的生物活性部分,氨基膦酸盐和苯并噻唑。该方法具有反应时间短、产率高、无溶剂条件以及通过避免有毒催化剂和溶剂在绿色方面易于处理等优点。4b 的晶体结构已通过 X 射线晶体学确定。该化合物在单斜空间群 C2/c 中结晶,晶胞参数 a = 21.9285(5) A, b = 10.3221(2) A, c = 18.5979(5) A, β = 108.759(3)°, V = 3985.99( 18) A3,Dcalc = 1.301 mg m−3,Z = 8。最终的 R 值为 0。0501 表示 3741 次反射。© 2012 Wiley Periodicals, Inc. 杂原子化学 24:58–65, 2013; 在 wileyonlinelibrary
