49603-23-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49603-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,0 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 49603-23:
(7*4)+(6*9)+(5*6)+(4*0)+(3*3)+(2*2)+(1*3)=128
128 % 10 = 8
So 49603-23-8 is a valid CAS Registry Number.

Metallic bismuth and tantalum mediated C-allylation of aldimines with allyl bromide

Bhuyan, Pulak J.,Prajapati, Dipak,Sandhu, Jagir S.

, p. 7975 - 7976 (1993)

A facile method for the synthesis of homoallyl amines using Bi/BU4NBr/MeCN and Ta/Bu4NBr/ THF system has been performed in a regiospecific manner.

Preparation of 2-azaallyl anions and imines from N-chloroamines and their cycloaddition and allylation

Pandiancherri, Shveta,Lupton, David W.

, p. 671 - 674 (2011/03/22)

Exposure of N-chloroamines to KOtBu or LDA, in the presence of PMDETA or HMPA, provides 2-azaallyl anions capable of π4s + π2s cycloaddition reactions with a range of olefins. Good yields were achieved with stabilised systems, however, they were more modest when accessing semi-stabilised 2-azaallyl anions. By modifying the reaction conditions, one-pot dehydrochlorination/allylation can also be achieved with a range of N-chloroamines.

Allylic Tantalums as Highly Imine-Selective Reagents

Shibata, Ikuya,Nose, Kyo,Sakamoto, Kazuya,Yasuda, Makoto,Baba, Akio

, p. 2185 - 2187 (2007/10/03)

A pratical method for the allylation of low electrophilic N-aliphatic imines was established by allylic tantalum. This is a superior methodology compared with conventional ones in terms of wide applicability to imines.
