2-Quinolylzincates were efficiently produced from the regioselective metalation reactions of quinoline with various organozincates as key intermediates. The four different types of title reactions of these intermediates under the presented reaction conditions allowed for the facile formation of the corresponding C-2 functionalized quinolines, which are not successfully accessed through typical zincation methods.

The catalytic promiscuity of the novel benzophenone C-glycosyltransferase, MiCGT, which is involved in the biosynthesis of mangiferin from Mangifera indica, was explored. MiCGT exhibited a robust capability to regio- and stereospecific C-glycosylation of 35 structurally diverse druglike scaffolds and simple phenolics with UDP-glucose, and also formed O- and N-glycosides. Moreover, MiCGT was able to generate C-xylosides with UDP-xylose. The OGT-reversibility of MiCGT was also exploited to generate C-glucosides with simple sugar donor. Three aryl-C-glycosides exhibited potent SGLT2 inhibitory activities with IC50 values of 2.6×, 7.6×, and 7.6×10-7-M, respectively. These findings demonstrate for the first time the significant potential of an enzymatic approach to diversification through C-glycosidation of bioactive natural and unnatural products in drug discovery. C-glycodiversification: MiCGT, as the first benzophenone C-glycosyltransferase (CGT) from Mangifera indica, showed robust regio- and stereospecific C-glycosylation activity for 35 structurally diverse acceptors with UDP-glucose or xylose. The aryl-C-glycoside 1 exhibited potent antidiabetic activity toward SGLT2.

(Chemical Equation Presented) Microwave irradiation of certain chloro-, bromo-, trifluoromethanesulfonyloxy- and nonafluorobutanesulfonyloxy-substituted quinolines in the presence of acetic anhydride and sodium iodide leads, via a trans-halogenation process, to the corresponding iodides in high yield. Related conversions involving pyridines and isoquinolines can also be achieved under similar conditions.

2-, 3- and 4-bromoquinolines were converted to the corresponding lithium tri(quinolyl)magnesates at -10°C by treatment with Bu3MgLi in THF or toluene. The resulting organomagnesium derivatives were quenched by various electrophiles to afford functionalized quinolines.
