Abstract

Sugar based γ-amino alcohol was used in asymmetric Michael addition of β-keto esters with nitroolefins for the first time affording the corresponding several chiral Michael adducts bearing quaternary chiral carbon center in moderate to good chemical yields and stereoselectivities (up to 98%, up to dr. 95:5, up to 84% ee).
