✦ Synopsis
The Diazo-quinone of P Q Q as a Possible Reagent for Mapping Quinoproteins by Photo-affinity Labeling PQQ is an organic redox cofactor found in a class of enzymes called quinoproteins. The synthesis and the photochemistry of the diazo-quinones of PQQ and PQQ-triester are described. The photogenerated Wo(ff--rearrangement products have been caught with water and methanol as model nucleophiles. The products show a strong fluorescence. The diazoquinone of PQQ may be considered as a possible reagent for mapping quinoproteins by photo-affinity labeling.
