Synthesis and fucosidase inhibitory study of unnatural pyrrolidine alkaloid 4-epi-(+)-codonopsinine

The total synthesis of enantiopure 4-epi-(+)-codonopsinine was achieved in 10 steps starting from d-ribose as a chiral building block. The key step involved a highly stereoselective nucleophilic addition of a Grignard reagent to a protected ribosylamine.
