Surface active agents derived from 1-O-Nsupalpha/sup-acetyl-L-aminoacyl ester 3-O-monoacyl glycerides and 1-O-Nsupalpha/sup-acetyl L-aminoacyl ester 2,3-O-diacyl glycerides type amino acids and the preparation thereof

摘要

Surfactants of the 1-O-Nalpha-acetyl-L-aminoacyl ester 3-O-monoacyl (or 2,3-O-diacyl) glyceride type are claimed. The surfactants have formula (I). R1 = acetyl; R2 = linear or branched chain, optionally substituted, saturated or unsaturated, or an optionally substituted aromatic group; R3 and R4 = hydrogen or a linear (preferably long) saturated or unsaturated chain; X = bromide, chloride, hydrogensulfate, acetate, trifluoroacetate, sodium or potassium; n = undefined. An Independent claim is also included for chemical or enzymatic synthesis of (I).
