  Synthesis and oral antiallergic activity of carboxylic acids derived from imidazo[2,1-c][1,4]benzoxazines, imidazo[1,2-a]quinolines, imidazo[1,2-a]quinoxalines, imidazo[1,2-a]quinoxalinones, pyrrolo[1,2-a]quinoxalinones, pyrrolo[2,3-a]quinoxalinones, and imidazo[2,1-b]benzothiazoles

  摘要：

  4H-Imidazo[2,1-c][1,4]benzoxazine-2-carboxylic acid (3) was found to possess potent activity in the IgE-induced rat passive cutaneous anaphylaxis model which may be predictive of clinical antiallergic activity. Compared to disodium cromoglycate (DSCG, 1), 3 was less active following iv administration but unlike DSCG showed very significant oral activity. To explore the structural requirements for this activity, a range of tricyclic compounds was prepared and their activities were measured. Individual 2-carboxylic acids derived from imidazo[1,2-a]quinolines, imidazo[1,2-a]quinoxalines, imidazo[1,2-a]quinoxalinones, pyrrolo[1,2-a]quinoxalinones, pyrrolo[2,3-a]quinoxalinones, and imidazo[2,1-b]benzothiazoles showed iv activities up to 10(3) times as potent as DSCG and many of them showed significant oral activity. From these, imidazo[1,2-a]quinoxaline-2-carboxylic acid 114 has been chosen for further development.

  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。
