A convenient process for the synthesis of glyoxylate-derived chloroformates has been developed. The approach involves the reaction of glyoxylate esters with triphosgene and pyridine in various solvent systems. These novel glyoxylate-derived chloroformates are multifunctional, possessing a chloroformate, ester, and haloalkyl moiety. Further elaboration via a thiocarbonate route afforded highly functionalized carboxylic acid-derived alkoxycarbonyl-chlorocarbonyloxy-methyl esters. Application of a benzyl glyoxylate-derived chloroformate to halofenozide was also accomplished, affording halofenozide-N-carbonyloxy-chloro/iodoacetic acid benzyl ester derivatives, which-were further derivatized to carboxylic acid-derived (halofenozide-N-carbonyloxy)-benzyloxycarbonyl-methyl esters. The trifunctional nature of the glyoxylate moiety was demonstrated through conversion of the benzyloxycarbonyl moiety of a carboxylic acid-derived (halofenozide-N-carbonyloxy)-benzyloxycarbonyl-methyl ester to its respective diethylamide.
