Indenones are synthesized using a practical and scalable method. The addition of Grignard reagents to indene-1,3-diones provides 2,3-disubstituted indenones through dehydrative aromatization. Significantly, a naturally occurring neo-lignan has been synthesised in one pot. Moreover, diallyl indenones have been utilized as ring-closing metathesis (RCM) precursors for synthesising fluorenones through
茚酮是使用实用且可扩展的方法合成的。将格氏试剂添加到茚-1,3-二酮中可通过脱水芳构化提供 2,3-二取代茚酮。值得注意的是,一种天然存在的新木脂素已在一锅中合成。此外,二烯丙基茚酮已被用作闭环复分解 (RCM) 前体,用于通过 RCM 芳构化序列合成芴酮。
