    Catalyst controlled straightforward synthesis of highly substituted pyrroles/furans via propargylation/cycloisomerization of α-oxoketene-N,S-acetals

    DOI: 10.1021/acs.joc.6b02367 Ganesh Chandra Nandi* and Soumini K. Abstract A facile and efficient InCl3 catalyzed one-pot synthesis of highly substituted pyrroles has been developed via a tandem propargylation/cycloisomerization reaction of α-oxoketene-N,S-acetals with propargyl alcohols. Notably, in the presence of Bronsted acid p-TSA.H2O, the reaction afforded the hydrolyzed product propargylated-1,3-dicarbonyl compounds, which upon treatment with Cs2CO3 […]

    Licarin B from Myristica fragrance improves insulin sensitivity by activating PPARγ and subsequently up-regulating GLUT4 via PI3/AKT Signaling Pathway

      Peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors regulating lipid and glucose metabolism. Ongoing drug discovery programs aim to develop partial PPARγ agonists devoid of the side effects of the marketed antidiabetic agents thiazolidinediones. Here, we evaluated the therapeutic potential of Licarin B (LB), a major bioactive constituent of Myristica fragrans in improving peroxisome […]
