(R,R)-(-)-N,N'-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-1,2-CYCLOHEXANEDIAMINO-MANGANESE(III) CHLORIDE Usage And Synthesis

Chemical Properties

(R,R)-(-)-N,N'-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-1,2-CYCLOHEXANEDIAMINO-MANGANESE(III) CHLORIDE is Dark brown powder or chunks

Uses

Salen (Mn)-catalyzed asymmetric epoxidation of unfunctionalized olefins. High enantioselectivities and yields are obtained for a variety of substrates, especially cis-alkenes. A few applications include the synthesis of the taxol side chain and cis-1-amino-2-indanol. Jacobsen′s catalyst has also been used in the asymmetric α-hydroxylation of silyl enol ethers. Catalyst for the enantioselective epoxidation of a variety of olefins.

Uses

(R,R)-(-)-N,N'-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-1,2-CYCLOHEXANEDIAMINO-MANGANESE(III) CHLORIDE is a coordinated compound of manganese and a salen-type ligand. It is also used as an asymmetric catalyst used to enantioselectively transform prochiral alkenes into epoxides.

Uses

Chiral catalyst for epoxidation of olefins.

Reactions

1. Catalyst for the conversion of olefins to chiral epoxides in high enantiomeric excess.
2. Pharmaceutically important, single enantiomer amino alcohols are efficiently produced from the corresponding chiral epoxide by acid or base-catalyzed epoxide ring-opening reactions.
3. symmetric Kinetic resolution of secondary alcohols in water.
4. Enantioselective Reformatsky reaction with ketones.
