Chemical Properties

White powder

Uses

Ligand for ruthenium-catalyzed greener amine synthesis by enamine reduction with hydrogen gas.Asymmetric Synthesis of (S)-3-Amino-4-methoxy-butan-1-ol by Way of Reductive Amination

Reactions

In many respects the catalytic profile of the MeOBIPHEP ligands is similar to that of other atropisomeric diphosphines such as binap and its many analogs. The nature of the PR2 group strongly influences the catalytic performance of the metal complexes. The rhodium and ruthenium MeO-BIPHEP catalysts are highly effective for the hydrogenation of various C=O, C=C and C=N bonds and several synthetically useful C-C coupling reactions. Ru and Ir catalyzed dynamic kinetic resolution for the synthesis of hydroxy, amino acid derivatives. 1.Ru-catalyzed asymmetric hydrogenation of ketones and alkenes. Ir catalyzed enantioselective hydrogenation of heteroaromatic compounds. Conjugate addition using 2-heteroaryl titanates and zinc reagents. Enantio- and regioselective heck-type reaction of aryl boronic acids with 2,3-dihydrofuran Rhodium-catalyzed carbonyl Z-dienylation. Rhodium-catalyzed asymmetric 1,4 addition of arylboronic acids to maleimides and enones.

Check Digit Verification of cas no

The CAS Registry Mumber 133545-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,4 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133545-16:
(8*1)+(7*3)+(6*3)+(5*5)+(4*4)+(3*5)+(2*1)+(1*6)=111
111 % 10 = 1
So 133545-16-1 is a valid CAS Registry Number.

Process for producing optically active gamma-butyrolactone

-

, (2008/06/13)

This invention provides a novel process for producing optically active 3-hydroxy-γ-butyrolactone in a short step, which is superior economically and in efficiency and industrially suitable by using a starting material which is inexpensive and easily available and reagents easy to handle. This invention relates to a process for producing optically active 3-hydroxy-γ-butyrolactone represented by formula I: wherein the symbol * means an asymmetric carbon atom, which comprises hydrogenating an optically active 4-substituted oxy-3-hydroxybutyrate represented by formula II: wherein R1 represents a C1-4 lower alkyl group, R2 represents a protective group for a hydroxyl group deprotected by hydrogenation with a heterogeneous hydrogenation catalyst, and the symbol * has the same meaning as defined above, in the presence of a heterogeneous hydrogenation catalyst and an acidic substance followed by deprotection and simultaneous ring closure thereof.
