  Syntheses of Cyclic Hydroxamic Acids and Lactams with 2,3-dioxo-1,4-benzoxazine skeleton

  摘要：

  Ethyl 2-nitrophenyl oxalate (1 a) and its 5-methoxy derivative (1 b) were subjected to catalytic hydrogenations over 3 % Pt (S) on carbon in different solvents. Thus, hydrogenation in acetic acid yielded 4-hydroxy-2,3-dioxo-1,4-benzoxazine (2a) and its 7-methoxy derivative (2 b) by reductive cyclization, the dehydro forms of the naturally occurring cyclic hydroxamic acids DIBOA and DIMBOA from Gramineae. In contrast, hydrogenation of esters 1 in methanol results in the formation of amides 3 by acyl group migration. On heating, amides 3 undergo lactonization to form lactone-lactames 4, which in turn undergo ring opening to give amides 3 when refluxed in ethanol.

  antiallergic activity using the rat passive cutaneous anaphylaxis (PCA) test. Many of the oxanilic acid esters are active orally, with the most active species having an aryl 2'-carbamoyl group and a 3'-methoxy group. Hydrolysis of the ester from the oxanilic ester moiety causes a loss of oral activity.
