本发明描述了萘并[1,2-B]呋喃、萘并[2,1-B]呋喃和呋喃并[3,2-c]色烯的有效和直接的合成。在氩气保护和无溶剂条件下,加热萘酚或4-羟基香豆素、异氰化物和醛的混合物,以优异的产率得到标题化合物。
An efficient and direct synthesis of naphtho[1,2-b]furans, naphtho[2,1-b]furans, and furo[3,2-c]chromenes is described. Heating a Mixture of a naphthol or 4-hydroxycoumarin, an isocyanide, and an aldehyde under an argon atmosphere and solvent-free conditions afforded the title compounds in excellent yields.
