136705-62-9 Usage

Reaction

The DUPHOS family of catalysts is highly efficient for the asymmetric hydrogenation of various substituted acetamidoacrylates and enol acetates yielding products of high enantiomeric excesses. Efficient ligand for the asymmetric hydrogenation of tetrasubstituted enamides. Forms superior catalysts for asymmetric reductive aminations. Catalyst used for the asymmetric hydrogenation of enol phosphonates. A novel enantioselective synthesis of β-amino alcohols and 1,2-diamines. Ligand for the catalytic asymmetric [4+1] cycloaddition of vinylallenes with CO. Ligand for the Rh-catalyzed asymmetric enyne cycloisomerization. Catalytic enantioselective addition of dialkylzinc to N-Diphenylphosphinoylimines. Palladium catalyzed asymmetric phosphination.

Check Digit Verification of cas no

The CAS Registry Mumber 136705-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,0 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136705-62:
(8*1)+(7*3)+(6*6)+(5*7)+(4*0)+(3*5)+(2*6)+(1*2)=129
129 % 10 = 9
So 136705-62-9 is a valid CAS Registry Number.

Preparation and use of C2-symmetric bis(phospholanes): Production of α-amino acid derivatives via highly enantioselective hydrogenation reactions

Burk, Mark J.,Feaster, John E.,Nugent, William A.,Harlow, Richard L.

, p. 10125 - 10138 (2007/10/02)

A new class of chiral C2-symmetric bis(phospholane) ligands has been prepared and used in rhodium-catalyzed asymmetric hydrogenation reactions. We describe a practical, one-pot procedure which utilizes enantiomerically pure 1,4-diol cyclic sulf
