1298133-38-6 Usage

Reaction

Enantioselective synthesis of chiral 1,2-amino alcohols via asymmetric hydrogenation of α-amino ketones with chiral spiro iridium catalysts.

Check Digit Verification of cas no

The CAS Registry Mumber 1298133-38-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,8,1,3 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1298133-38:
(9*1)+(8*2)+(7*9)+(6*8)+(5*1)+(4*3)+(3*3)+(2*3)+(1*8)=176
176 % 10 = 6
So 1298133-38-6 is a valid CAS Registry Number.

An additional coordination group leads to extremely efficient chiral iridium catalysts for asymmetric hydrogenation of ketones

Xie, Jian-Hua,Liu, Xiao-Yan,Xie, Jian-Bo,Wang, Li-Xin,Zhou, Qi-Lin

supporting information; experimental part, p. 7329 - 7332 (2011/09/16)

What a turnover! An efficient chiral iridium catalyst that bears a tridentate spiro aminophosphine ligand catalyzes the asymmetric hydrogenation of ketones with excellent enantioselectivities (up to 99.9 % ee) and extremely high turnover numbers (TONs; as high as 4 550 000). Copyright
