FACILE PREPARATION OF DEOXYIODOCELLULOSE AND ITS CONVERSION INTO 5,6-CELLULOSENE
Ishii, Tadashi
, p. 63 - 70 (2007/10/02)
Treatment of 6-chloro-6-deoxycellulose with sodium iodide in 2,5-hexanedione gave 6-deoxy-6-iodocellulose; > 80 percent of the chlorine atoms were replaced. 6-Deoxy-6-iodo-D-glucose was identified by g.l.c.-m.s. in hydrolyzates of deoxyiodocellulose.Acetylated 6-deoxy-6-iodocellulose was converted almost quantitatively into 5,6-cellulosene acetate, wich was characterized by hydrolyzing the product and converting the resultant dicarbonyl sugar into an isopropylidene acetal 10.The changes of molecular-weight distribution during iodination and dehydroiodination were investigated by gel-permeation chromatography.
Process for the preparation of chlorodeoxysugars
-
, (2008/06/13)
A process for the preparation of a chlorodeoxy derivative of a reducing aldose having a primary hydroxy group in an exocyclic -CH2 OH group, in which the said primary hydroxy group is replaced by a chlorine atom to give a chlorodeoxy reducing sugar with a free anomeric center, characterized in that the free reducing sugar is reacted with a reagent comprising an N,N-dialkyl (methaniminium) chloride obtained by reacting an N,N-dialkyl formamide with a chlorinating agent.
