organocatalytic homodimerization of 2-cyclohexenone has been studied and it is concluded that the mechanism of the reaction follows competing pathways involving either a two-step imine/enamine addition or a concerted Diels–Alder cycloaddition where the ultimate product distribution is dependent upon the ratio of the organocatalyst to 2-cyclohexenone and a base present.
研究了2-环己烯酮的l-脯氨酸有机催化均二聚反应,得出的结论是,反应机理遵循竞争性途径,涉及两步亚胺/烯胺加成或一致的Diels-Alder环加成,其中最终产物的分布取决于取决于有机催化剂与2-环己烯酮和存在的碱的比例。
