At last! The addition of bisulfite to olefins, discovered over a century ago, remains the most straightforward approach to aliphatic sulfonic acids. A catalytic enantioselective procedure has now been realized that employs a bifunctional aminothiourea catalyst (see picture). Sulfonic acids were obtained from chalcones in high yields and high enantioselectivity and in both configurations.
终于!在一个多世纪前发现,将亚硫酸氢盐添加到烯烃中仍然是最简单的脂族磺酸方法。现在已经实现了使用双功能氨基硫脲催化剂的催化对映选择性程序(见图)。从查耳酮以两种产率高产率和高对映选择性地获得磺酸。
