Abstract
The reaction between cyclic 1,2-sulfites and two imide and two sulfona mide nucleophiles has been Investigated in order to develop a procedur e for the enantioselective preparation of N-protected vicinal amino al cohols. The results show that both imide and sulfonamide anions react with cyclic sulfites, yielding the desired products. In some cases the regioselectivities are low, and for the sulfonamides products origina ting from nucleophilic addition to the sulfite sulfur are observed.
