, p. 201/[729]-208/[736] (2004)
The synthesis of a novel chiral non-racemic TADDOL derivative is presented and discussed. When the material is placed in a suitable nematic host it forms a chiral nematic phase which has an independence of the helical twisting power (HTP) with temperature

Synthesis of aryl alkyl ethers by alkylation of phenols with quaternary ammonium salts
Maras, Nenad,Polanc, Slovenko,Kocevar, Marijan
experimental part, p. 29 - 36 (2010/09/05)
Phenolic compounds can be efficiently O-methylated with tetramethylammonium chloride in diglyme or polyethyleneglycol (PEG) at temperatures of 150-160 °C and in the presence of either K2CO3 or NaOH. When applying benzyl-trimethylammonium chloride as a reagent, the benzylation and methylation of phenols occurs, with the benzylation product always predominating. With allyl-substituted phenols as substrates and using NaOH as a base it was possible to achieve both the alkylation and the double-bond isomerization of the allyl group to obtain (E/Z)-propenyl-substituted methyl and benzyl aryl ethers in a single preparative step.
