A general and efficient protocol for the high-pressure-promoted asymmetric hetero-Diels-Alder reactions of oxindoles has been developed. These reactions can be realized by using chiral thiourea-derived organocatalysts, and the desired adducts are obtained in good to high yields with good to moderate enantioselectivity.
针对羰基吲哚的高压促进不对称异狄尔斯-阿尔德反应,我们开发了一种通用而高效的方案。这些反应可通过使用源自手性硫脲的有机催化剂来实现,并能以良好至中等对映选择性获得高产率的所需加合物。
