We report the one-pot synthesis of N-CF3 heteroaryl amides (NTFMHA) from heteroaryl carboxylic acids and sterically hindered isothiocyanates, including various amino acid analogues, in the presence of AgF. The key to this reaction is the utilization of free heteroaryl acyl chlorides, rather than their corresponding hydrochloride salts. This method represents a complementary method of our previous work
我们报道了在 AgF 存在下,由杂芳基羧酸和位阻异硫氰酸酯(包括各种氨基酸类似物)一锅法合成N -CF 3杂芳基酰胺(NTFMHA)。该反应的关键是利用游离杂芳基酰氯,而不是其相应的盐酸盐。该方法代表了我们之前工作的补充方法,并且能够对各种以前无法接近的结构进行修饰,包括α-叔胺和N -CF 3修饰的药物。
