Résumé : |
Anionic heterogemini surfactants with –COOH, –SO3H and –PO(OH)2headgroups in combination were synthesized from Corynomicolic acid derivatives having R = C11H23. The –SO3H headgroup was obtained by the successive conversion of OH → OMs → SCN → SH → –SO3H. The PO(OH)2headgroup was introduced by the conjugate-addition to E-isomer of α,β-unsaturated ester derived from Corynomycolic acid ester. Heterogemini surfactant with –SO3H and –PO(OH)2headgroups was also synthesized from phosphonate analog of Corynomycolic acid. The stereoisomers (syn- and anti-isomers) of heterogemini surfactants were separately prepared except for heterogemini surfactants with –COOH and –PO(OH)2headgroups. Effects of variation and stereochemistry of two anionic headgroups on their surfactant properties were also studied on the basis of surface tension measurements. |
