Glycidol derivatives bearing ester, ether or silyl functionality upon treatment with trifluoroacetic acid (TFA) in the presence of a halide anion (e.g., Bu4NX; X = Cl, Br or I) at room temperature undergo regioselective and stereospecific openi

A chemoselective route for the synthesis of 1-O-alkylglycerols chimyl (1), batyl (2), and selachyl (3) is reported. These compounds can be naturally isolated from shark liver oil and the skin of animals such as stingrays and chimeras and exhibit potential anti-fouling activity. The synthetic approach developed in this work included two distinct methods of preparation. The first was based on solvent-free reactions catalyzed by onium quaternary salts (N and P) and ionic liquids; the second methodology was based on a series of one-pot reactions.
Synthesis and characterization of nonconventional surfactants of aromatic amino acid-glycerol ethers: Effect of the amino acid moiety on the orientation and surface properties of these soap-type amphiphiles

The synthesis, characterization, and surface properties of soaptype amphiphiles comprising alkyl chains of 10-16 carbon atoms linked through an ether group to a glycerolamino acid hydrophilic head group is described. The surface properties of members of this series derived from histidine and tyrosine were compared with those of phenylalanine and tryptophan derivatives described previously and with those of conventional soaps. In all cases, the amino acid derivatives showed superior surface properties, and an interesting differentiation was discovered regarding the orientation of tryptophan derivatives.
Influence of α-branched fatty acid chains on the thermotropic behaviour of racemic 1-O-hexadecyl-2-acyl-glycero-3-phosphocholines

Phosphatidylcholines containing an α-branched palmitic acid ester linked to position C2 of the glycerol backbone were synthesized and characterized using differential scanning calorimetry and X-ray diffraction. As the length of the sidegroup substituted on the palmitic acid chain is changed, the calorimetric parameters pass through a minimum. The polymorphic behaviour is different when the sidegroup is larger, or smaller, than propyl. The comparison of the physicochemical parameters of isomers differing in the bonding of the branched chain fatty acid to the glycerol backbone (to position C1 or C2, respectively) shows that the chains are nonequivalent.
