The difluoromethylene (CF2) group in aliphatic chains: Synthesis and conformational preference of palmitic acids and nonadecane containing CF2 groups

The syntheses of palmitic acids and a nonadecane are reported with CF 2 groups located 1,3 or 1,4 to each other along the aliphatic chain. Specifically 8,8,10,10- and 8,8,11,11-tetrafluorohexadecanoic acids (6b and 6c) are prepared as well as the singly modified analogue 8,8-difluorohexadecanoic acid (6a). Also 8,8,11,11-tetrafluorononadecane (27) is prepared as a pure hydrocarbon containing a 1,4-di-CF2 motif. The modified palmitic acids are characterized by differential scanning calorimetry (DSC) to determine melting points and phase behaviour relative to palmitic acid (62.5 °C). It emerges that 6c, with the CF2 groups placed 1,4- to each other, has a significantly higher melting point (89.9 °C) when compared to the other analogues and palmitic acid itself. It is a crystalline compound and the structure reveals an extended anti-zig-zag chain. Similarly 8,8,11,11- tetrafluorononadecane (27) adopts an extended anti-zig-zag structure. This is rationalized by dipolar relaxation between the two CF2 groups placed 1,4 to each other in the extended anti-zig-zag chain and suggests a design modification for long chain aliphatics which can introduce conformational stability.

Method for synthesizing fluorescent dye intermediate aldehyde by hydroformylation of 1,3-diene compound

The invention discloses a method for synthesizing a fluorescent dye intermediate aldehyde by hydroformylation of 1,3-diene compound. The method comprises the following steps: S1, sequentially adding 0.01 mmol (1 mol%) of [Rh(cod)Cl]2, 0.1 mmol of a phosphine ligand(P/Rh=10/1) and 1 mmol of diene into a reaction flask, adding 1 ml of a solvent DMF, putting the reaction flask into a high-pressure reaction kettle, after the reaction is finished, transferring a mixed solution into a 25 mL glass bottle with 200 microliters of n-tridecane as an internal standard by using a rubber head dropper, and detecting; and S2, determining the product yield and the structure through a gas chromatograph and a nuclear magnetic resonance spectrum, wherein the obtained olefin conversion rate is larger than 99%, the aldehyde yield ranges from 61% to 99%, and the regioselectivity of the product aldehyde ranges from 70/30 to 100/0. According to the method disclosed by the invention, the separation and purification steps of aldehyde products are simplified, and the substrate of the dialkene hydroformylation reaction is excellent in universality.

Synthesis and biological evaluation of some undecanone derivatives

The total synthesis of Ardisinone E [15, 1-(2,4,6-trihydroxy phenyl)-11-(2-hydroxyphenyl)-undecan-1-one], a natural diarylundecanone, isolated from Ardisia arborescens, was accomplished along with 16 new diarylundecanone analogs (18a–p), by modified Wittig reaction. The structures of the compounds were confirmed by 1H, 13C and mass spectral data. Compound 15 showed potent cytotoxic activity with an ED50 of 4.19 μg/mL in brine shrimp lethality assay model. Compounds 18c, 18e, 18j, 18k, 18l, and 18m exhibited strong anti-oxidant activity with IC50 values of 18.75, 12.28, 18.35, 11.04, 12.05, and 11.32 μg/mL, respectively, in NBT free radical assay. Compounds 18e, 18k, and 18m also showed significant 5-lipoxyganase enzyme inhibitory potential with IC50 values of 12.8, 15.23, and 15.23 μg/mL, respectively.
