Reduction: The fifteen possible hydroxy- and polyhydroxypteridines
were reduced, chemically and catalytically.
Potassium borohydride, sodium dithionite, and potassium (or
sodium) amalgam were used as the chemical reducing agents.
Hydrogenation over palladium, platinum, and Raney-nickel were
used for catalytic reductions. Except 2,4,7-trihydroxypteridine
all these were successfully reduced by at least one
of the above methods. Hyuroxypteridines lacking a hydroxy
group in the...[Show more]
