174023-92-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 174023-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,0,2 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 174023-92:
(8*1)+(7*7)+(6*4)+(5*0)+(4*2)+(3*3)+(2*9)+(1*2)=118
118 % 10 = 8
So 174023-92-8 is a valid CAS Registry Number.

Iridium-catalyzed asymmetric allylic substitutions with bulky amines/oxidative double bond cleavage - Entry into the reetz synthesis of amino alcohols

Seehafer, Kai,Malakar, Chandi C.,Bender, Markus,Qu, Jianping,Liang, Chen,Helmchen, Günter

, p. 493 - 501 (2016/02/18)

Branched allylic amines were prepared by Ir-catalyzed enantioselective allylic aminations with the bulky N-nucleophiles HN(Boc)2 and HNBn2. The products were transformed into N-protected amino aldehydes, which were either reduced or coupled diastereoselectively with organometallic compounds to give vicinal amino alcohols. A formal synthesis of the neurokinin receptor antagonist (+)-L-733060 was carried out as an application. Ir-catalyzed enantioselective allylic aminations with bulky N-nucleophiles HN(Boc)2 and HNBn2 gave N-protected allylic amines, which were transformed into N-protected chiral amino aldehydes. These are useful chiral building blocks as previously demonstrated by Reetz et al. A formal synthesis of the neurokinin receptor antagonist (+)-L-733060 was carried out as an application.
