5,5,5-hexafluoropentane-2,4-dione) and various benzylamines were systematically studied. The results obtained lead to the development of a generalized and practical method for large-scale synthesis of the corresponding imines/enamines, useful starting materials for preparation fluorinated amines and amino acid.
在高度亲电的含氟二羰基化合物(4,4,4-三氟乙酰乙酸乙酯,3,3,3-三氟丙酮酸乙酯和1,1,1,5,5,5-六氟戊烷-2,4-之间的反应中的化学和区域选择性对二酮)和各种苄胺进行了系统的研究。获得的结果导致开发了用于大规模合成相应的亚胺/烯胺的通用且实用的方法,所述亚胺/烯胺是用于制备氟化胺和氨基酸的有用的起始原料。
