133609-19-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133609-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,0 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133609-19:
(8*1)+(7*3)+(6*3)+(5*6)+(4*0)+(3*9)+(2*1)+(1*9)=115
115 % 10 = 5
So 133609-19-5 is a valid CAS Registry Number.

Novel synthesis of O-allylated oxime ethers based on allylic substitution with oximes

Miyabe, Hideto,Matsumura, Akira,Yoshida, Kazumasa,Yamauchi, Masashige,Takemoto, Yoshiji

, p. 2123 - 2126 (2004)

The palladium or iridium-catalyzed O-allylic substitution of oximes provides a new method for direct preparation of the O-allylated oxime ethers from oximes.

Utility of the iridium complex of the pybox ligand in regio- and enantioselective allylic substitution

Miyabe, Hideto,Matsumura, Akira,Moriyama, Katsuhiko,Takemoto, Yoshiji

, p. 4631 - 4634 (2007/10/03)

(Chemical equation presented) The viability of the iridium complex of pybox as chiral catalyst in allylic substitutions and the enantioselective synthesis of branched products was studied. Among several chiral ligands evaluated, the iridium complex of pybox having a phenyl group catalyzed the reaction with high activity to form the branched amines with good enantioselectivities when hydroxylamine, amine, and aniline were employed as a nucleophile. The allylic substitution with oximes proceeded smoothly to give the branched oxime ethers with good enantioselectivities.
