heteroaryl glycosyl sulfones undergo desulfonylative C−C cross-coupling with aryl-substituted nucleophiles or electrophiles through two complementary catalytic systems. The reactions offer access to a wide variety of C-aryl glycoside products with high diastereoselectivity.
An array of C-aryl furanosides was prepared in good yields from furanosyl halides and aryl Grignard reagents in Et2O using PPh3 as a catalyst. (C) 2013 Elsevier Ltd. All rights reserved.
