Abstract

The invention concerns compounds of formula (I) wherein: A represents R1 or (O)R1 where R1 represents an alkyl group comprising 1 to 30 carbon atoms, linear or branched, saturated or unsaturated, capable of being partly or totally substituted by Hal where Hal represents —Cl,—Br, or —F, and of being interrupted by one or several units selected among —O—,—S—,—C(O)—,—NR3C(O)—, —Ph(R4)n— and —CH2—CH2—O)n′—, wherein R3 represents or —CH2)n″—CH where n″=0 to 17; R4 represents, —CH3,—CH2H5,—C3H7 and n=0 to 4 and n′=1, 2, or 3, or R1 represents a cyclanic radical with diterpene or triterpene root; and R2 represents a C1−C11 linear or branched alkyl group. The invention also concerns a method for obtaining said compounds, compositions containing them and their use as surfactant, and in enzymatic processes using a chitinase, in particular N-acetylglucosaminidase.
