Abstract An efficient and mild synthesis of 2-(guaiazulen-1-yl)furans, starting from easily accessible 1-(3-aryl-2-cyanopropenoyl)guaiazulenes, tributylphosphine and acyl chlorides, is described. The strategy employs the intramolecular Wittig protocol as a key step to append the crucial furan ring, leading to the highly functional furans in good yields.
摘要描述了一种从轻而易举的1-(3-芳基-2-氰基丙烯酰基)愈创木酚烯,三丁基膦和酰氯开始的高效温和合成2-(愈创木酚-1-基)呋喃的方法。该策略采用分子内Wittig方案作为附加关键呋喃环的关键步骤,从而以高收率获得了功能强大的呋喃。
