Uses

L-Valine tert-butyl ester hydrochloride is a protected form of L-Valine (V094205). L-Valine is an essential amino acid that is used as an ingredient in cosmetic formulations, pharmaceuticals, and animal feed products. L-valine is also important for growth and ammonia detoxification in humans.

Check Digit Verification of cas no

The CAS Registry Mumber 13518-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13518-40:
(7*1)+(6*3)+(5*5)+(4*1)+(3*8)+(2*4)+(1*0)=86
86 % 10 = 6
So 13518-40-6 is a valid CAS Registry Number.

Effect of substituents on enantioselectivity in chiral oxazaborolidine mediated asymmetric ketone reduction reaction

Balakrishnan,Ananthi,Velmathi

experimental part, p. 1157 - 1164 (2011/10/13)

Various new chiral ligands have been synthesized by the condensation of different esters of L-Valine with different substituted salicylaldehydes in order to find the most effective catalyst for the enantioselctive ketone reduction. Chiral amine synthesized from L-Valine methyl ester and 5-chloro salicylaldehyde is found to catalyse the enantioselective reduction of prochiral ketone with high yield (99%) and enantiomeric excess (91%) with 20 mol% of the catalyst using borane dimethylsulphide as a stoichiometric reducutant. Different subsituted prochiral ketones have also been reduced in high yield upto 90% and the corresponding secondary alcohols are formed with good enantiomeric excess upto 99%. The mechanism of this reduction can be very well explained by considering a plausible mechanism for the CBS catalyst.
