| Abstract: | The reactions of methyl and ethyl esters of valine with m-bromobenzaldehyde and p-chlorobenzaldehyde in absolute methanol in the presence of magnesium sulfate yielded the corresponding azomethines (CH3)2CHCH(COOR1)N=CHR2 (R1 = CH3, C2H5; R2 = 3-BrC6H4, 4-ClC6H4); their reduction with sodium borohydride gave N-benzyl derivatives of valine esters, (CH3)2CHCH(COOR1)NHCH2R2.Translated from Zhurnal Obshchei Khimii, Vol. 74, No. 11, 2004, pp. 1855–1857.Original Russian Text Copyright © 2004 by Yakubovich, Zhavnerko, Shirokii, Knizhnikov.This revised version was published online in April 2005 with a corrected cover date. |
