New cardiolipin analogs synthesized by phospholipase D-catalyzed transphosphatidylation

Cardiolipin (CL) and related diphosphatidyl lipids are hardly accessible because of the complexity of their chemical synthesis. In the present paper, the transphosphatidylation reaction catalyzed by phospholipase D (PLD) from Streptomyces sp. has been proven as an alternative enzyme-assisted strategy for the synthesis of new CL analogs. The formation of this type of compounds from phosphatidylcholine was compared for a series of N- and C2-substituted ethanolamine derivatives as well as non-charged alcohols such as glycerol and ethylene glycol. The rapid exchange of the choline head group by ethanolamine derivatives having a low molecular volume (diethanolamine and serinol) gave rise to an efficient production of the corresponding CL analogs. In contrast, the yields were comparably low in the reaction with bulky nitrogenous acceptor alcohols (triethanolamine, tris(hydroxymethyl)aminomethane, tetrakis(hydroxyethyl)ammonium) or the non-charged alcohols. Therefore, a strong dependence of the conversion of the monophosphatidyl to the diphosphatidyl compound on steric parameters and the head group charge was concluded. The enzyme-assisted strategy was used for the preparation of purified diphosphatidyldiethanolamine and diphosphatidylserinol.

Effect of hydrogen bond of hydroxyl-functionalized ammonium ionic liquids on cycloaddition of CO2

A synergistic effect of the hydrogen bond on the cycloaddition of CO2 and epoxides to form cyclic carbonates was investigated through experimental study and characterization. A highly effective homogeneous system of hydroxyl-functionalized quaternary ammonium ionic liquids with a different number of the hydroxyl group in the cation was developed for the fixation of CO2 to form cyclic carbonates. A mechanism via the hydrogen bond activation for the cycloaddition was proposed based on both experimental data and modeling. This research enhances the understanding of the promotion of reaction via hydrogen bonding and forms the basis for the rational design of catalytic systems for the fixation of CO2 into organic compounds.
