Fig. 2: Substrate scope of aldimines 2a.

From: Synthesis of chiral anti-1,2-diamine derivatives through copper(I)-catalyzed asymmetric α-addition of ketimines to aldimines

Fig. 2

Both aromatic aldimines and aliphatic aldimines are employed. a1a: 0.2 mmol, 2: 0.3 mmol. Isolated yield. Dr determined by 1H NMR analysis of the crude reaction mixture. Enantioselectivity determined by chiral-stationary-phase HPLC analysis. b4 equiv 2. cThe reaction is performed with 10 mol % mesitylcopper and 10 mol % (R,RP)-TANIAPHOS in THF at RT for 8 h.
