Continuous flow synthesis of indoles by Pd-catalyzed deoxygenation of 2-nitrostilbenes with carbon monoxide

The palladium-catalyzed deoxygenation of o-vinylnitrobenzenes employing carbon monoxide as a terminal reductant produces indoles in a continuous flow environment. The reaction proceeds with catalyst loadings of 1 to 2 mol% Pd(OAc)2 in the presence of suitable ligands/additives and generates carbon dioxide as the only stoichiometric side-product. The reductive cyclization proceeds in a clean fashion with high initial reaction rates in the pressurized flow reactor, ultimately leading to deposition of catalytically inactive palladium(0) inside the channels of the flow device, allowing for an efficient catalyst recovery. A variety of o-vinylnitrobenzenes (o-nitrostilbenes and -styrenes) were converted to the corresponding indoles within 15 to 30 min at a reaction temperature of 140 C to furnish products in good to excellent yields (10-20 bar CO pressure). Mechanistic aspects and the scope of the transformation are discussed.

Taste masking of a drug by pH-responsive coordination polymer-coated mesoporous silica nanoparticles

We developed a simple and efficient method for fabricating a taste-masked oral drug delivery system (DDS) that regulates the release of unpleasant drug taste via the change in pH value in the physiological environment of the alimentary canal. In this drug delivery system, a pH-sensitive metal-organic coordination polymer (CP), Fe-4,4?-bipyridine (Fe-bipy) complex, works as a taste-masker. The pH-sensitive Fe-bipy was grafted onto the mesoporous silica nanoparticles (MSNs) containing the model bitter drug mequindox (MEQ) in its mesopores through metal-organic coordination cross-linking, resulting in the CP-coated nanodrug MSN-NH2-MEQ@Fe-bipy. In artificial saliva (pH 6.6), Fe-4,4?-bipyridine CPs effectively prevent the leaking of the loaded guest molecule MEQ. On the other hand, in artificial gastric fluid (pH 1.0), the coordination bonds of the Fe-4,4?-bipyridine complex were broken, leading to the release of MEQ molecules from MSN-NH2-MEQ@Fe-bipy. The results indicate that the simple and efficient preparation method for taste-masked MSN-NH2-MEQ@Fe-bipy could provide new insights into taste-masking technology by using pH-responsive smart nanomaterials.
