Oxidation (with such reagents as iron(III) chloride, potassium dichromate, silver oxide or nitrous acid) of 4,7-, 6,7-, and 5,6-dihydroxy-, and 5,6-dimethoxy-benzimidazoles gives the corresponding quinones. A 5-methyl group is oxidized by permanganate to carboxy (74CRV279). In the presence of copper(II)-piperidine or -dimethylamine complexes oxygen... [Pg.429]

When [l-carboxy- C]o-succinyl benzoate is administered to plants of Catalpa ovata (Bignoniaceae), it is incorporated into a-lapachones (such as 45), catalponol (46), and catalpalactone (47). Examination of the ratio in catalponol (46) after administration of [l-carboxy- C,2 - H2]o-succinylbenzoate reveals that the two protons at the 2 -posi-tion are both retained in the 3-position of catalponol (Fig. 6.9). Thus, prenylation occurs at the 2-position and does not involve an aromatic compound such as 1,4-dihydroxy-2-naphthoic acid (DHNA) (40) (Inouye and Leistner, 1988). 2-Carboxy-4-oxotetralone (COT) (43) or 2-carboxy-4-hy-droxy-l-tetralone (48) are possible acceptors for the prenyl unit. When 2-carboxy-4-hydroxy-l-tetralone (48), or its methyl ester, was introduced into the plant, the prenyl derivatives of 2-carboxy-4-oxotetralone (COT) (43) and 2-car-boxy-4-hydroxy-l-tetralone (50) were isolated as intermediates (Inouye and Leistner, 1988). [Pg.82]
