One-pot syntheses of fluorescent o-aminobenzoates, o-aminopyridine carboxylates, and a 2′-amino-[1,1′-biphenyl]-2-carboxylic acid are described. Carbodiimides are used as the source of the 2-amino function which inserts onto an aromatic ring using SNAr reaction conditions. This method proceeds regiospecifically with a range of 2-fluoroaromatic acids or esters bearing further aryl fluorine, trifluoromethyl
的荧光单釜合成ö -aminobenzoates,ø氨基吡啶羧酸盐和2'-氨基- [1,1'-联苯] -2-羧酸进行说明。碳二亚胺用作插入到使用了S的芳香环的2-氨基功能的源Ñ的Ar反应条件。该方法用一系列带有另外的芳基氟,三氟甲基和氰基取代基的2-氟芳族酸或酯进行区域专一性处理。
