Abstract:
Rhamnolipids are biosurfactants with many applications, arising from their inherent biological activity and their potential as bioremediation agents. Herein, we report the synthesis of four rhamnolipid derivatives in which the ester linkage connecting the two lipid chains in the natural compound is replaced with amide, ketone, ether, or hydrocarbon functional groups. Such compounds are anticipated to have enhanced hydrolytic stability and thus be useful probes of rhamnolipid-mediated biology and biotechnology.

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
