Convenient, facile, and alternate synthesis of medicinally important flavones is reported. The 2-hydroxychalcones derived from condensation between acetophenones and salicylaldehyde, underwent oxidative cyclization on heating in the presence of catalytic iodine, generating diversified flavones under solvent-free conditions. Eleven compounds have been synthesized in good to excellent yields and their
据报道,医学上重要的黄酮类化合物的合成方便,简便。由苯乙酮和水杨醛之间的缩合反应生成的2-羟基查耳酮在催化性碘的存在下,在加热条件下进行氧化环化反应,在无溶剂条件下生成多种黄酮。已经以良好的产率和优异的产率合成了11种化合物,并描述了它们的形成机理。
