An efficient and direct synthesis of naphtho[1,2- B]furans, naphtho[2,1- B]furans, and furo[3,2- C]chromenes is described. Heatinga mixture of a naphthol or 4-hydroxycoumarin, an isocyanide, andan aldehyde under an argon atmosphere and solvent-free conditionsafforded the title compounds in excellent yields.
描述了萘并[1,2-B]呋喃、萘并[2,1-B]呋喃和呋喃[3,2-C]色烯的有效和直接合成。在氩气气氛和无溶剂条件下加热萘酚或4-羟基香豆素、异氰化物和醛的混合物以优异的产率提供标题化合物。
