A convenient approach to 4,5-disubstituted 3-hydroxymethyl-1,2,4-triazoles as well as to the corresponding 3-chloromethyl and 3-carboxaldehyde derivatives was developed starting from 3-mercapto-1,2,4-triazoles which can, in turn, be readily obtained from acyl hydrazines and isothiocyanates.
以 3-巯基-1,2,4-三唑为起点,开发了一种简便的方法来制备 4,5-二取代的 3-羟甲基-1,2,4-三唑以及相应的 3-氯甲基和 3-甲醛衍生物,而 3-巯基-1,2,4-三唑又很容易从酰基肼和异硫氰酸盐中获得。
