Dunlap, Norma K.,Mergo, Wosenu,Jones, James M.,Carrick, Jesse D.

, p. 3923 - 3925 (2002)

Oxidative cleavage of a series of glycols using NaIO4 on silica gel in the presence of a series of stabilized ylides provides access to a number of synthetically useful alkenes. The ease and general utility of this reaction is demonstrated here using several carbohydrates and amino acid derived glycols.
