122539-37-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122539-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,5,3 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 122539-37:
(8*1)+(7*2)+(6*2)+(5*5)+(4*3)+(3*9)+(2*3)+(1*7)=111
111 % 10 = 1
So 122539-37-1 is a valid CAS Registry Number.

Organocyanocopper-Trifluoroborane Mediated 1,3-Chirality Transfer Reaction of γ-(Mesyloxy)-α-alkyl α,β-Enoates for the Construction of Chiral Quaternary Carbon Centers with High Optical Purity

Ibuka, Toshiro,Akimoto, Naoshige,Tanaka, Miwa,Nishii, Shinji,Yamamoto, Yoshinori

, p. 4055 - 4061 (1989)

The mesylates of chiral γ-hydroxy-α-methyl (E)-α,β-enoates undergo 1,3-chirality transfer to form chiral α-alkyl-α-methyl (E)-β,γ-enoates with high optical purity using organocyanocopper-trifluoroborane reagents.The degree of asymmetric induction, regiochemistry, and chemoselectivity has been found to be uniformly high.THF or mixed solvents involving THF, a γ-(methylsulfonyl)oxy leaving group, and organocopper-Lewis acid regents prepared from CuCN, RLi, and BF3*Et2O were found to be necessary to ensure the success of the preparation of chiral quaternarycarbon centers with high optical purity via the 1,3-chirality transfer.The present efficient procedure is compatible with a variety of oxygenated groups such as mesyl, benzyl, tert-butyldimethylsilyl, and isopropylidene functions.
