Chiral pyrrolidines synthesis from carbohydrates

BUCHANAN ETAL. Synthesis of Chiral Pyrrolidines from Carbohydrates 109... 

Two syntheses and one formal synthesis of (+)-preussin have been reported using sugars as chiral pool building blocks. In these syntheses parts of the sugar backbone have been implemented into the preussin skeleton. All four pyrrolidine carbon atoms stem from the carbohydrate. As a consequence, the two carbon-nitrogen bonds (N/C-2 and N/C-5) of the pyrrolidine ring...
