Practical Continuous-Flow Trapping Metalations of Functionalized Arenes and Heteroarenes Using TMPLi in the Presence of Mg, Zn, Cu, or la Halides
Becker, Matthias R.,Knochel, Paul

The flow metalation of various arenes and heteroarenes involving an in situ trapping with metal salts (ZnCl2. LiCl, MgCl2, CuCN. LiCl, LaCl3. LiCl) under very convenient conditions (0 ?C, 40 s) is reported. The resulting Mg, Zn, Cu, or La organic species are trapped with various electrophiles in high yields. In several cases, unusual kinetically controlled regioselectivities are obtained. All these flow metalations can be scaled up simply by extending the reaction time and without further optimization. The reaction scope of such flow metalations is considerably broader than that of the corresponding batch procedures.

experimental part, p. 1192 - 1198 (2012/04/23)
Three novel gem-dimethyl C-glucosides were designed as sodium-glucose co-transporter 2 (SGLT2) inhibitors, and their syntheses started from D-glucose and three 2-substituted-5-bromobenzoic acids were achieved via a facile 8-step protocol, with the key step being anhydrous aluminum chloride-catalyzed Friedel-Crafts alkylation of tertiary alcohols and phenetol. These three SGLT2 inhibitors were evaluated in vivo with a mice oral glucose tolerance test (OGTT), and the anti-hyperglycemic activities of all these three compounds were comparable with that of the positive control Dapagliflozin.
