General description

Methyl 2-aminobenzoate reacts with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulphide at 140°C to yield 1,2-dihydro-2-(p-methoxyphenyl)-4H-3,1,2-benzothiazaphosphorin-4-thione-2-sulfide and dimethyl-4-methoxyphenylphosphonotrithioate.

Application

Methyl 2-aminobenzoate has been used in the synthesis of novel 4-chloro-2-mercaptobenzenesulfonamide derivatives.

A 2:1 complex between cyclomaltoheptaose (beta-cyclodextrin) and N-methylanthranilic acid has been studied in the solid state. The inclusion complex belongs to the triclinic system (space group P1) with unit cell dimensions a=15.2773(15)A, b=15.4710(15)A, c=17.9627(18)A, alpha=99.632(5) degrees , beta=113.416(5) degrees

Bacillus megaterium, isolated in a screening process from topsoil, was used for N-demethylation of natural N-methyl methyl anthranilate to produce natural methyl anthranilate. Maximal productivity of 70 mg/L/day was achieved under laboratory-scale conditions without further optimization. No byproducts were observed.
