Reactions

1. A versatile ligand for asymmetric catalysis.
(a) Conjugate addition of hydrazoic acid to unsaturated imides. 2. Enantioselective conjugate cyanation of unsaturated imides. 3. Cobalt catalyzed enantioselective alpha chlorination and fluorination of beta-ketoesters.

Chemical Properties

(R,R)-(-)-N,N'-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-1,2-CYCLOHEXANEDIAMINE is yellow powder

Uses

(R,R)-(-)-N,N'-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-1,2-CYCLOHEXANEDIAMINE is a versatile ligand used in the preparation of Jacobsen's catalyst.

Uses

Versatile ligand for asymmetric catalysis. Ligand used for preparing Jacobsen′s catalyst suitable for enantioselective epoxidation of olefins lacking functional groups.

Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.

Biochem/physiol Actions

α-amylase catalyzes the hydrolysis of internal α-1,4-O-glycosidic bonds in starches to release α-anomeric sugars.
