Bates, Gareth W.; Triyanti; Light, Mark E.; Albrecht, Markus; Gale, Philip A. published the artcile< 2,7-Functionalized Indoles as Receptors for Anions>, Product Details of C19H34O2, the main research area is indole carboxamide amido ureido thioureido preparation structure anion complexation; stability constant phosphate carboxylate chloride amido ureido thioureido indolecarboxamide; titration NMR anion complexation indolecarboxamide amido ureido thioureido derivative; hydrogen bond phosphate carboxylate indolecarboxamide amido ureido thioureido derivative; crystal structure indolecarboxamide amido ureido thioureido derivative; mol structure indolecarboxamide amido ureido thioureido derivative.
A series of 7-amido- and 7-ureido- and 7-thioureido-1H-indole-2-carboxamide derivatives were prepared by reduction and acylation of the corresponding 7-nitro-1H-indolecarboxamides; the compounds exhibit binding properties towards dihydrophosphate, acetate, benzoate and chloride ions. Amidation of 7-nitro-1H-indole-2-carboxylic acid by amines RNH2 gave N-R-7-nitro-1H-indole-2-carboxamides (8a,b; R = Bu, Ph), which were reduced to the corresponding N-R-7-amino-1H-indole-2-carboxamides (9a,b). Reaction of 9a,b with BuCOCl, PhCOCl, PhCH2COCl, BuNCO, PhNCO and PhNCS gave N-R-7-R1NH-1H-indole-2-carboxamides (1 R = Bu, R1 = BuCO; 2 R = Ph, R1 = PhCO; 3 R = Ph, R1 = PhCH2CO; 4 R = Bu, R1 = BuNHCO; 5 R = Ph, R1 = PhNHCO, 6 R = Ph, R1 = PhNHCS). Stability constants were measured in aqueous solution for complexation of 1-6 with H2PO4-, MeCO2-, PhCO2- and Cl- anions. Anion complexation studies show a marked difference in the mode of interaction of carboxylates with indole-ureas vs. indole-amides.
