Catalytic Asymmetric

The asymmetric Michael addition/desymmetrization reaction catalyzed by a N,N′-dioxide-Sc(iii) complex was realized, leading to the succinimides with two kinds of stereogenic elements—atom chirality and axial chirality in up to 99% yield, 99% ee and >19 : 1 d.r.

Efficient Construction

Cu(i)-catalyzed asymmetric Michael addition of cyclic ketimino esters with alkylidene malonates has been developed for efficient construction of β-branched α-amino acids containing adjacent quaternary and tertiary stereogenic centers in good yields with excellent diastereo-/enantioselectivities.
