Synthesis and characterization of biphenyl liquid crystal based on natural molecules and 2(5H)-furanone moiety

Using 4′-hexyloxybiphenyl-4-ol and N-(5-alkoxy-3-bromo-2(5H)- furanonyl) amino acids as reactants, a series of novel biphenyl liquid crystal compounds containing natural molecule moieties, such as menthol, borneol, and amino acids, were synthesized via esterification. The structures of all novel compounds were confirmed by FTIR, 1H NMR, 13C NMR, MS, and elemental analysis, and the liquid crystal properties of target compounds were characterized with DSC, XRD, and POM. The introduction of hexyloxy made the biphenyl esters have a potential to appear in mesomorphic phase and have a higher Tm, and bornyl moiety was more beneficial for the liquid crystal performance than a menthyl unit. Most compounds were mesomorphic phase liquid crystal molecules, and POM and XRD showed that they existed in smectic phase. These researches provide a theoretical basis for the synthesis of biphenyl ester liquid crystal materials via the utilization of 2(5H)-furanone derivates and natural molecules.

Concise synthesis of chiral 2(5H)-furanone derivatives possessing 1,2,3-triazole moiety via one-pot approach

Combining three bioactive units, such as 2(5H)-furanone, 1,2,3-triazole, and amino acid together into one potential drug molecule with polyfunctional groups, a series of new chiral 2(5H)-furanone derivatives containing 1,2,3-triazole moiety have been designed and synthesized from (5S)-5-alkoxy-3,4-dibromo-2(5H)-furanones, amino acids, propargyl bromide, and organic azides via the sequential three steps, including asymmetric Michael addition-elimination, substitution, and click reaction. The latter two steps, substitution and click reaction could proceed smoothly in a one-pot process. Furthermore, the target products could be directly synthesized via a four-component one-pot approach.

Synthesis of N-[5-alkoxy-2(5H)-furanonyl] amino acid propargyl esters

Using K2CO3 as a base and CH3CN as solvent, different kinds of N-[5-alkoxy-2(5H)-furanonyl] amino acids were reacted with propargyl bromide via substitution reaction at 40 °C to give 16 N-[5-alkoxy-2(5H)-furanonyl] amino acid propargyl esters with the yields of 44-85% (mostly over 74%). The structures of all newly synthesized compounds were elucidated and confirmed by FTIR, UV, 1H NMR, C NMR, MS, and elemental analysis. The rapid, efficient, and brief synthesis of the series propargyl esters with multiple bioactive units, will afford not only a basis for the activity test of potential drug molecules, but also an important synthetic strategy for 2(5H)-furanone derivatives with polyfunctional groups.
