Abstract: Quaternary ammonium salts containing gem-dichlorocyclopropane and 1,3-dioxolane groups were synthesized in high yield. The reactions of dichlorocarbonation of styrene and O-alkylation of 2,2-dimethyl-4-hydroxymethyl-1,3-dioxolane in the presence of quaternary ammonium salts were studied. It was established that in the O-alkylation reaction, compounds containing cycloacetal and allyl moieties have the maximum efficiency in the series of catalysts studied. The structures of the isolated salts were proved by 1H and 13C NMR spectroscopy.

Two hybrid fluorinated double-chain surfactants with a diglucosylated polar head were synthesized. The apolar domain consists of a perfluorohexyl main chain and a butyl hydrogenated branch as a side chain. They were found to self-assemble into small micel

Bifidobacteria are dominant members of the microbial community in the intestinal tract of infants, and studies have shown that glycolipids extracted from the cell surface of these bacteria elicit beneficial immune responses. Accordingly, the identification and structural characterization of glycolipids from the cell wall of bifidobacteria is the first step in correlating glycolipid structure with biological activity. Using whole cell MALDI as a screening tool, we herein present for the first time the identification and structural elucidation of the major polar lipids from Bifidobacterium longum subs. infantis. The lipids identified include an unprecedented plasmenyl cyclophosphatidic acid and a mixed acetal glycolipid, with the latter subsequently being isolated and found to suppress the innate immune response.
