成功开发了一种PPh3催化环丙烯酮与卤代烷的开环加成反应, 为室温下合成具有E型立体选择性的α,β-二取代丙烯酸酯提供了一种简洁实用的方法. 机理研究表明, α,β-不饱和丙烯酸酯中乙烯基上的氢原子和酯基中的一个氧原子均源自反应溶剂二甲基亚砜(DMSO)中所含的水. 此外, 通过开展克级规模实验及产物的衍生化修饰, 进一步拓展了该方法在有机合成中的应用潜力.

A PPh3-catalyzed ring-opening addition reaction of cyclopropenones with alkyl bromides has been successfully established. This reaction offers a concise and practical approach for the assembly of α,β-disubstituted acrylates with exclusive E-stereoselectivity at room temperature. Mechanistic investigations indicated that both the hydrogen atom on vinyl group and one oxygen atom on ester group of α,β-disubstituted acrylates derive from H2O in dimethyl sulfoxide (DMSO). Furthermore, a gram-scale experiment and late-stage modification of the products were accomplished, thereby expanding the application potential of this methodology in organic synthesis.

Key words: cyclopropenone, phosphine-catalysis, α,β-disubstituted acrylates, ring-opening addition reaction
