We disclose a novel high yielding and highly enantioselective chiral calcium VAPOL phosphate-catalyzed chlorination of 3-substituted oxindoles with N-chlorosuccinimide (NCS). The reaction conditions are also shown to be effective for the catalytic enantioselective Michael addition of 3-aryloxindoles to methyl vinyl ketone.
我们公开了一种新型高产、高对映选择性的手性钙 VAPOL 磷酸催化的 3-取代氧吲哚与 N-氯代丁二酰亚胺(NCS)的氯化反应。反应条件也被证明对 3-芳基氧吲哚与甲基乙烯基酮的催化对映选择性迈克尔加成反应有效。
