The macrocyclic tetraamides 8a-e were obtained in good yields by bis-alkylation of the potassium salts of the appropriate bisphenols 7a-c with the dihalo compounds 2a,b. Similarly, macrocyclic tetraamides with pendant hydroxy group 18a,b were prepared by the nucleophilic reaction of the potassium salts of 7a,b with the dihalo compound 10. Acylation of 18a,b with chloroacetyl chloride gave the corresponding
通过适当的双酚7a-c的钾盐与二卤代化合物2a、b的双烷基化,以良好的产率获得大环四酰胺8a-e。类似地,具有侧羟基的大环四酰胺18a、b通过7a、b的钾盐与二卤代化合物10的亲核反应制备。18a、b用氯乙酰氯酰化得到相应的酯19a、b。化合物 19a、b 与不同的仲胺反应以 50-65% 的产率得到相应的套索大环 20a-d 和新型双大环 21。
