Anthranilic acid derivatives exhibiting fungicidal properties and useful as synthesis intermediates have the formula: ##STR1## wherein R is selected from the group consisting of a hydrogen atom; a --COOR.sup.3 group and a --CH.sub.2 OH group; R.sup.1 and R.sup.2 are the same or different and selected from the group consisting of a hydrogen atom and alkyl and cycloalkyl groups (provided that R.sup.1 and R.sup.2 are not both hydrogen atoms), or R.sup.1 and R.sup.2, together with the nitrogen atom to which they are attached, form a non-aromatic heterocyclic ring structure; R.sup.3 is selected from the group consisting of a hydrogen atom and an alkyl group; R.sup.4 is selected from the group consisting of a hydrogen atom, a halogen atom and a hydroxyl group; R.sup.6 is selected from the group consisting of a hydrogen atom and a halogen atom; and R.sup.5 is selected from the group consisting of a hydrogen atom, a halogen atom, and nitro, thiocyano and formyl groups. A process for production of these compounds by self-condensation of a substituted aminocrotonate by phosphorous oxychloride is also disclosed.
