Noviose, a rare sugar moiety present in many biologically interesting molecules such as novobiocin and tiacumicin was obtained through formal synthesis in (+)- and (−)-forms starting from commercially available (−)-pantolactone in an enantiodivergent manner.
Noviose (1), the sugar moiety of the antibiotic Novobiocin(1), has been synthesized enantioselectively from the readily available(2) chiral building block 2 in seven steps. (C) 1998 Elsevier Science Ltd. All rights reserved.
