Novel α,α-difluorohomophthalimides 2 were prepared by reacting N-substituted 2-halobenzamides with the α,α-difluoro Reformatskii reagent BrZnCF2CO2Et (3) in the presence of CuBr at room temperature. The synthesis involves a CuBr-mediated cross-coupling of 3 with aryl iodides or activated aryl bromides, followed by a spontaneous cyclization of the ethyl 2-benzamido-α,α-difluoroacetate intermediates
新颖α,α-difluorohomophthalimides 2通过反应制备ñ -取代2-卤代苯甲酰胺与α,α-二氟Reformatskii试剂BrZnCF 2 CO 2的Et(3)中的CuBr的在室温下的存在。合成过程涉及CuBr介导的3与芳基碘化物或活化的芳基溴化物的交叉偶联,然后在室温下自生环化2-苯甲酰胺基-α,α-二氟乙酸乙酯中间体。还通过使3当量的3进行反应,制备了带有能够充当羧酸生物等排体的酸性酰亚胺质子的N-未取代的α,α-二氟邻苯二甲酰亚胺2(R'= H)。与母体2-碘苯甲酰胺。其他芳基碘化物,例如3-碘-咪唑并[1,2-α]吡啶也用于串联偶联-环化反应。

An iridium-catalyzed, reductive alkylation of abundant tertiary lactams and amidesusing 1–2 mol % of Vaska’s complex (IrCl(CO)(PPh3)2), tetramethyldisiloxane (TMDS), and difluoro-Reformatsky reagents (BrZnCF2R) for the general synthesis of medicinally relevant α-difluoroalkylated tertiary amines is described. A broad scope (46 examples), including N-aryl- and N-heteroaryl-substituted lactams, demonstrated
