Synthesis derivatives of 5, 6 -isopropylidene –N-{Methyl, Ethyl, Isopropyl, Isobutyl, Isopentyl, 2-phenylethyl}-gluconamide

Abstract

Many new derivatives for L-ascorbic acid were prepared after closed the positions
(2, 3, 5, and 6) in the L-ascorbic acid. Then its reaction with several amino acids (glycine,
alanine, valine, leucine, phenylalanine). TLC, Elemental analysis, FTIR and H1.NMR
spectroscopy, has characterized the synthesized compounds
