DOI: 10.1007/s00158-019-02232-8
Abstract: In this article, a Stackelberg game theoretic approach is used for multi-objective optimal synthesis of four-bar mechanisms for path generation. Two objective functions, namely, tracking error (TE) and transmission angle’s deviation from 90° (TA), are… read more here.

DOI: 10.1016/j.tet.2018.01.053
Abstract: Abstract Because of the structural similarity between 5,18-diHETE and anti-inflammatory resolvin E2, synthesis of 5,18-diHETE was studied. Methyl (R)-3-hydroxyvalerate was converted to the (R)-C9–C20 phosphonium salt via alkylation of the derived iodide with propargyl alcohol… read more here.

DOI: 10.1021/acs.est.7b01179
Abstract: Monoterpenes, a major class of biogenic volatile organic compounds, are known to produce oxidation products that further react with sulfate to form organosulfates. The accurate quantification of monoterpene-derived organosulfates (OSs) is necessary for quantifying this… read more here.

DOI: 10.1039/d2ra00499b
Abstract: The asymmetric total synthesis of four lignans, dimethylmatairesinol, matairesinol, (−)-niranthin, and (+)-niranthin has been achieved using reductive ring-opening of cyclopropanes. Moreover, we performed bioassays of the synthesized (+)- and (−)-niranthins using hepatitis B and influenza… read more here.
