Abstract

"PROCESSO PARA A OXIDAçãO SELETIVA DE áLCOOIS PRIMáRIOS DE OLIGOSSACARìDEOS PARA FORMAR OS DERIVADOS DE áCIDO CARBOXìLICO CORRESPONDENTES DE áLCOOIS" A invenção refere-se a um processo para a oxidação seletiva de álcoois primários de oligossacarídeos para formar os derivados de ácido carboxílicos correspondentes dos álcoois usando quantidades catalíticas de um radical livre de alquil nitroxila di-terciária, caracterizado pelo fato de que 1,3-dibromo-5,5-dimetilidantoína ou 1,3-dicloro-5,5-dimetilidantoína é usado como oxidante e a reação é efetuada em condições neutras a básicas em um pH < 10. O processo da invenção é útil para a produção de oligossacarídeos (parcialmente protegidos) compreendendo grupos carboxilatos tanto intermediários como produtos finais.
