THE FIRST OF THESE ROUTES INVOLVES THE FORMATION OF A 2-N2,2-DIACYLOXY) ACETAMIDOPHENYL ARYL KETONE FROM GLYOXYLIC ACID AND AN ARYL PHENYL KETONE VIA EITHER A 2,2-DIACYLOXY ACETYL HALIDE OR A 2,2-DIACYLOXY ACETYL ANHYDRIDE, CONVERSION THEREOF TO THE CORRESPONDING 2-(2-ACYLAMIDO-2-HYDROXY)ACETAMIDOPHENYL ARYL KETONE DIRECTLY OR VIA THE 2-(2,2-DIHYDROXY) ACETAMIDOPHENYL ARYL KETONE, FORMATION OF THE CORRSPONDING 2-(2-ACYLAMIDO-2-HALO) ACETAMIDOPHENYL ARYL KETONE, AND CONVERSION TO THE 2-(2-ACYLAMIDO-2-AMINO) ACETAMIDOPHENYL ARYL KETONE. THE SECOND ROUTE FORMS THE 2-(2,2-DIHYDROXY) ACETAMIDOPHENYL ARYL KETONE BY REACTING A 2,3-DICARBOXYLICACYL TARTARIC ANHYDRIDE WITH A 2-AMINOPHENYL ARYL KETONE TO OBTAIN A 2-(3-CARBOXY-2,3ACYLOXY) PROPIONAMIDOPHENYL ARYL KETONE, SELECTIVELY HYDROLYZING THE SO-OBTAINED KETONE AND SELECTIVELY OXIDIZING THE PRODUCT WITH A VIX GLYCOL CLEAVING AGENT.

The first of these routes involves the formation of a 2-(2,2-diacyloxy)acetamidophenyl aryl ketone from glyoxylic acid and an aryl phenyl ketone via either a 2,2-diacyloxy acetyl halide or a 2,2-diacyloxy acetyl anhydride, conversion thereof to the corresponding 2-(2-acylamido-2-hydroxy) acetamidophenyl aryl ketone directly or via the 2-(2,2-dihydroxy)acetamidophenyl aryl ketone, formation of the corresponding 2-(2-acylamido-2halo)acetamidophenyl aryl ketone, and conversion to the 2-(2acylamido-2-amino)acetamidophenyl aryl ketone. The second route forms the 2-(2,2-dihydroxy) acetamidophenyl aryl ketone by reacting a 2,3-dicarboxylicacyl tartaric anhydride with a 2aminophenyl aryl ketone to obtain a 2-(3-carboxy-2,3acyloxy)propionamidophenyl aryl ketone, selectively hydrolyzing the so-obtained ketone and selectively oxidizing the product with a vic glycol cleaving agent.
