REDUCTION OF METHYL BENZOYLFORMATE BY REDUCED NICOTINAMIDE ADENINE DINUCLEOTIDE MODEL IN THE PRESENCE OF RHODIZONIC ACID

Endo, Takeshi,Takada, Tadayoshi,Okawara, Makoto

, p. 615 - 618 (1986)

The reduction of rhodizonic acid (RA) with 1-benzyl-1,4-dihydronicotinamide (BNAH; NADH model) was carried out at room temperature to obtain tetrahydroxy-p-quinone (THQ) and hexahydroxybenzene (HHB) by two-electron and four-electron reductions, respectively.The reduction of methyl benzoylformate with BNAH proceded smoothly in the presence of RA, although it could not be reduced at all without RA.
