1557101-75-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1557101-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,7,1,0 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1557101-75:
(9*1)+(8*5)+(7*5)+(6*7)+(5*1)+(4*0)+(3*1)+(2*7)+(1*5)=153
153 % 10 = 3
So 1557101-75-3 is a valid CAS Registry Number.

Practical and efficient synthesis of chiral 2,4-disubstituted oxazolines from β-phosphonoamides

Avalos-Alanis, Francisco G.,Hernandez-Fernandez, Eugenio,Hernandez-Romero, Rocio,Lopez-Cortina, Susana,Ordonez, Mario,Garcia-Barradas, Oscar,Lagunas-Rivera, Selene

, p. 156 - 162 (2014/02/14)

Herein we report a practical and efficient method for the synthesis of optically active 2,4-disubstituted oxazolines (S)-1a-h in good to excellent yields. The target compounds were prepared in good yield through the Horner-Wadsworth-Emmons reaction of β-phosphonoamide 3 bearing l-phenylalaninol with commercially available aryl aldehydes followed by the cyclodehydration of the corresponding N-(cinnamoyl)-(S)-phenylalaninol derivatives (S)-2a-h. Additionally, the cyclodehydration of β- phosphonoamide (S)-3 followed by the Horner-Wadsworth-Emmons reaction of β-phosphono-oxazoline (S)-4 with aryl aldehydes also gave the 2,4-disubstituted oxazolines (S)-1a-h.
