Functionalized aryl-β-C-glycoside synthesis by Barbier-type reaction using 2,4,6-triisopropylphenyllithium
摘要:
We developed an efficient synthetic route for functionalized aryl-beta-C-glycosides, which are difficult to prepare by conventional methods. An aryl halide having an ester, cyano, or carbonyl group was treated with 2,4,6-triisopropylphenyllithium in the presence of a delta-lactone (Barbier-type reaction conditions) to afford a coupling product. The following deoxygenation gave the desired aryl-beta-C-glycoside in good yield. (C) 2015 Elsevier Ltd. All rights reserved.
