✦ Synopsis

Photosensitized oxygenation of a-keto carboxylic acids in the presence of diazo compounds afforded the corresponding carboxylic acids and carbon dioxide in high yields; oxidative decarboxylation by carbonyl oxides occurred. Hydroxylations catalyzed by several dioxygenases require cc-keto carboxylic acid as co-factor. Half a mole of molecular oxygen is introduced into substrate ( S-H ) while the other half is taken up by the cr-keto carboxylic acid which undergoes oxidative decarboxylation; in this system the cr-keto

a-Oxo-carboxylic acids undergo photo-oxidative decarboxylation from both C-l and C-2 positions, and reaction does not involve singlet oxygen: a mechanism involving an electron transfer reaction is postulated.
