A highly efficient asymmetric Michaeladdition of 1-acetylindolin-3-ones to α,β-unsaturatedaldehydes is developed to afford 2-substituted indolin-3-one derivatives in high yields (up to 94%) with good stereoselectivities (up to 11:1 dr and 96% ee). The Michael adducts can be transformed into substituted cyclopentyl[b]indoline compounds conveniently without racemization.

The first asymmetric Michael addition of 1-acetylindolin-3-ones to beta-nitrostyrenes has been developed. 2-Substituted indolin-3-one derivatives were obtained with excellent yields (up to 99%) and good stereoselectivities (up to 28:1 dr and 92% ee), which could be transformed into 2-functionalized indoles easily without racemization. This achievement might further contribute to the chemistry and pharmacology of indole-related compounds.
