Autor: Roger Meuwly, Andrea Vasella

Publikováno v: Helvetica Chimica Acta. 67:1568-1571

Partially protected 4- or 5-hydroxy-sugar oximes were transformed into 5- or 6-membered 1-C-nitroglycosyl chlorides, respectively, by reaction with NaOCl under phase-transfer conditions. With the exception of the oxidation of the gluco-derivative 1 g

Autor: Andrea Vesella, Roger Meuwly, Bernrd Aebischer

Publikováno v: Helvetica Chimica Acta. 67:2236-2241

The 1-C-nitroglycosyl chloride reacted with the anions form 2-nitropropane, nitromethane, and diethyl malonate, to give the chain-extended products 2 (81%), 5 (72%), and 6 (83%), respectively. Treatment of the 1-C -nitroglycosyl bromide 7 by the lith
