Trifluoromethyl substituted heterocycles have been prepared by condensation of the new β-trifluoracetyl-lactams 1 and -benzolactams 2 with methylhydrazine and benzamidine as bis-nucleophiles without opening of the lactam structure.
通过使新的β-三氟乙酰基-内酰胺1和-苯并内酰胺2与作为双亲核试剂的甲基肼和苯甲condensation缩合而没有打开内酰胺结构,可以制备三氟甲基取代的杂环。
