o-Benzenedisulfonimide has been used for the first time as a Brønsted acid catalyst to induce electrocyclization of dienones into cyclopentenones (Nazarov reaction). The catalyst has been used in various organic solvents or under solvent-free conditions and it is entirely recoverable from the reaction mixture. The versatility and the effectiveness of the proposed procedure is demonstrated on a wide range of both activated and inactivated substrates.
邻苯二磺酰亚胺首次被用作布伦斯特酸催化剂,用于引发二烯酮的电环化反应,生成环戊烯酮(纳扎罗夫反应)。该催化剂可用于多种有机溶剂或无溶剂条件下,且可从反应混合物中完全回收。该方法的多功能性及有效性已在多种活性和非活性底物上得到验证。
