Publikováno v: Synlett. 27:1551-1556

An efficient method has been developed for the synthesis of C-glycosyl amino acids through a tandem nucleophilic opening–cyclization of an l -ido-bisepoxide with the anion of Schollkopf’s bislactim. A masked amine was introduced at the CH2C1-posi

Publikováno v: Carbohydrate research. 342(15)

The preparation of 6,6,1′,1′,6′,6′-hexadeutero sucrose is reported. The synthesis is based on a triple oxidation of a protected sucrose 6,1′,6′-triol to the corresponding 6,1′,6′-tricarboxylic acid or ester, followed by reduction with
