Abstract
Sugar-derived tetrol, non-ionic amphiphilic amine-esters are prepared facilely and efficaciously in a few steps. The process is initiated by the esterification of a sugar-derived tetrol with a fatty acid chloride, then, undergoing triflate esterification followed by nucleophilic displacement of the aforementioned hydrophilic amine. Each synthetic pathway is efficient and affords modest to high yields of target amphiphiles, which are valorized as practicable surfactant surrogates to petroleum incumbents.
