52694-55-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52694-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,6,9 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52694-55:
(7*5)+(6*2)+(5*6)+(4*9)+(3*4)+(2*5)+(1*5)=140
140 % 10 = 0
So 52694-55-0 is a valid CAS Registry Number.

Tertiary amine synthesis: Via reductive coupling of amides with Grignard reagents

Xie, Lan-Gui,Dixon, Darren J.

, p. 7492 - 7497 (2017/10/30)

A new iridium catalyzed reductive coupling reaction of Grignard reagents and tertiary amides affording functionalised tertiary amine products via an efficient and technically-simple one-pot, two-stage experimental protocol, is reported. The reaction-which can be carried out on gram-scale using as little as 1 mol% Vaska's complex [IrCl(CO)(PPh3)2] and TMDS as the terminal reductant for the initial reductive activation step-tolerates a broad range of tertiary amides from (hetero)aromatic to aliphatic (branched, unbranched and formyl) and a wide variety of alkyl (linear, branched), vinyl, alkynyl and (hetero)aryl Grignard reagents. The new methodology has been applied directly to bioactive molecule synthesis and the high chemoselectivity of the reductive coupling of amide has been exploited in late stage functionalization of drug molecules. This reductive functionalisation of tertiary amides provides a new and practical solution to tertiary amine synthesis.
