A novel, one-step synthesis of 5-deazaflavin developed, in which a [4+2]cycloaddition is presumably involved, to give the 5-deazaflavin derivative in moderate yield. This methodology was successfully applied to the stepwise preparation of its thio analogue, 5-deaza-10-thiaflavin, whose 1, 5-dihydro derivative was transformed into the corresponding sulfone in good yield.
开发了一种新颖的一步合成5-去氟黄素的方法,其中可能涉及[4+2]环加成反应,以中等产率得到5-去氟黄素衍生物。这种方法成功应用于其硫类类似物5-去氟-10-硫黄素的逐步制备,其1,5-二氢衍生物转化为对应的磺酰胺,产率良好。
