Novel pentacenequinone derivatives 3, 7, and 10 have been synthesized via Suzuki−Miyaura coupling. Derivatives 3 and 7 having OTBS groups undergo irreversible fluoride-induced cyclization to substituted higher quinones in the presence of TBAF in dry THF using one-pot, two-step strategies in moderate yields. These functionalized higher quinone derivatives are freely soluble in THF and DMSO and can be
新颖并五苯衍生物3,7,和10已经通过铃木-宫浦偶联合成。具有TBBS基团的衍生物3和7在干燥的THF中在TBAF存在下使用一锅两步策略以中等收率经历了不可逆的氟化物诱导的环化反应,生成取代的高级醌。这些官能化的高级醌衍生物可自由溶于THF和DMSO,可用作合成高级并苯衍生物的前体。
