A general and efficient protocol for the high-pressure-promoted hetero-Diels-Alder reactions of activated ketones has been developed. The reactions are successfully achieved by thiourea-derived organocatalysts, and the desired adducts, convenient precursors of δ-lactones, are obtained in good to high yields.
已经开发了一种用于活化酮的高压促进的异-Diels-Alder 反应的通用和有效的协议。该反应通过
硫脲衍生的有机催化剂成功实现,并以良好到高产率获得所需的加合物,即 δ-内酯的方便前体。
