Syntheses of C-5-spirocyclic C-glycoside SGLT2 inhibitors
摘要:
Several syntheses of C-5-spirocycle-containing C-glycosides are discussed. A multigram-scale synthesis capitalizing on a one-pot aldol-Cannizzaro sequence is described. Spiro oxetane formation using an unprotected penta-ol C-glycoside as substrate is also exemplified. Functional assessment of these compounds for potency and selectivity was evaluated at human SGLT2 and SGLT1. (C) 2010 Elsevier Ltd. All rights reserved.
