DOI:10.1039/c39840000702
日期:——
Treatment of 1-acetoxy-1H-2-benzopyran-4-one with either base or heat generates the parent 2-benzopyrylium-4-oxide system which gives intermolecular cycloadducts with a variety of dipolarophiles, including olefins.
用碱或热处理1-乙酰氧基-1 H -2-苯并吡喃-4-酮产生母体2-苯并吡啶-4-氧化物体系,该体系产生分子间环加合物与多种双极性亲核试剂,包括烯烃。
