Studies of α- Thiocarbonyl Phosphonic Acid Derivative Quinazolone Analogues Containing Phosphorus

Abstract

Abstract: Aseries of N-substituted 1-methoxycarbonylmethyl-3-substituted-2,4-dioxo-1,3,2-benzodiazaphosphorin-2-carboxamides(2a_2q) have been designed and synthesized by two methods, and their structures were confirmed by elemental analysis, NMR, IRand MS. On the basis of X-ray diffraction analysis, we discussed stereochemistry of the title compounds, and studied their ¹H NMRmagnetic nonequivalent phenomenon which agrees with the results of X-ray analysis. The preliminary bioassay shows that some of the title compounds have a good plant hormone activity.

Key words: α-Thiocarbonyl phosphonic acid, Quinazolone analogues containing phosphorus, Reaction, Stereochemistry, Biological activity
