title: Antigravitropic activity of 2-(2-arylamino-1,2-dioxoethyl) benzoic acid methyl esters.
abstract: Methylation of 1,3-dihydro-1-hydroxy-3-oxo-1-isobenzofurancarboxamides (A-I) yields 2-(2-arylamino-1,2-dioxoethyl)benzoic acid methylesters. The esters 1-7 allowed the evaluation of the intrinsic activity of 2-(2-arylamino-1,2-dioxoethyl)benzoic structure, to whom the antigravitropic effect of the carboxamides A-I may be probably assigned. The comparison of activities of methylesters 1-7 (B) and 8-14 (C) shows how conformational differences as those between the arylamino-1,2-dioxoethylic portion of B and the arylamino-2-oxoethylic portion of C may deeply effect phytotropin interaction with the receptor site.
