Pyrimido[4,5-b]quinoline-2(3H),4(10H)-diones (5-deazaflavins) and related compounds oxidize alcohols under alkaline conditions in the dark to yield the corresponding carbonyl compounds, while they themselves are hydrogenated to the 1,5-dihydro-derivatives. The substituent effect in the 5-deazaflavin series was examined in terms of the oxidizing ability toward benzyl alcohol. In some cases, the benzyl
Pyrimido [4,5 - b ] quinoline-2(3 H),4(10 H)-二酮(5-deazaflavins)和相关化合物在黑暗中于碱性条件下将醇氧化生成相应的羰基化合物,而它们本身是氢化成1,5-二氢衍生物。根据对苄醇的氧化能力检查了5-脱氮黄素系列中的取代基作用。在某些情况下,5-脱氮唑黄素的苄醇氧化已显示可自动循环,并获得了大于100%的苯甲醛收率(基于5-脱氮黄素)。
