Dear all,
Thanks for the answers to my question about deoxygenation of sugar
derivatives. Though I have examined this topic very briefly, it seems there
are not yet promising methods without using tin and a thiocarbonyl
derivative, which can be applied to, at least, a minimum amount of product
(for example, 10 grams if you are using the deoxysugar as a starting
material for a synthetic route). The articles of Rizzo (JOC 1996, 61, 6092;
ibid 1997, 62, 8257) make also use of a mechanism based on radicals, but
this time photochemically induced, so it seems very difficult to apply the
method to a larger quantity of product.
I hope to obtain more information on this reading more recent papers.
Best regards,
Dr. Jacobo Cruces
