An asymmetric rhodium(III)-catalyzed C−H bond addition to aldimines followed by subsequent intramolecular cyclization to form chiral isoindolinones has been achieved by using a chiral directing group. Various substituted benzamides and aldimines have been smoothly transformed to the corresponding products in up to 68 % yield with up to 93 % ee.
通过使用手性导向基团,不对称铑 (III) 催化的 C-H 键加成到醛亚胺,随后分子内环化形成手性异吲哚啉酮。各种取代的苯甲酰胺和醛亚胺已顺利转化为相应的产品,产率高达 68%,ee 高达 93%。
