Synthesis of Surfactants and Polymers

Acylation of o-glucono-1,4-lactone and o-glucono-1,5-lactone with A-(l 1-unde-cenoyl)-l,3-thiazolidine-2-thione in the presence of triethylamine gave 6-(9-unde-cenoyl ester as the single product. In the case of the 1,5-lactone, isomerization to the 

Another type of amphiphUic-like structure in which an aldonolactone moiety is present was prepared by acetalization of D-glucono-1,4-lactone (24) and D-glucono- 

In the context of the synthesis of carbohydrate-based amphiphilic (alkylsulfanyl) polyols, Beaupere and co-workers explored the access to 5- and 6-alkylsulfanyl derivatives of pentono- and hexonolactones and their corresponding 1-(alkylsulfanyl) pentitol or l-(alkylsulfanyl)hexitol [38, 39]. Bromolactones 27 and 30 were treated 

The use of carbohydrates as raw materials for the generation of polymers has attracted particular interest in the last two decades not only because of concerns related with sustainability and biocompatibility, but also due to the unique mechanical and physical properties that the sugar units may provide to the material (for 

Aldonolactones serve as suitable monomers for the generation of homo- and copolymers, especially through ring-opening polymerization (ROP). Among them are the carbohydrate-analogs of s-caprolactone, i.e., aldono-1,6-lactones. The first example of such derivatives and further ROP was reported by Galbis and co-workers [61], see also chapter, Synthetic polymers from readily available monosaccharides
