Synthetic Studies on the Carbohydrate Moiety of Amipurimycin
摘要:
The carbohydrate core of amipurimycin in its fully acetylated form was synthesized in 24 steps starting from commercially available methyl 4,6-O-benzylidene--D-glucopyranoside to give an overall yield of 1.5%. The late-stage intermediates involved were suitable for total synthesis of amipurimycin. It was further discovered that the branches and the protecting groups on the sugar rings of involved intermediates had a significant influence on their conformations, which in turn resulted in new and interesting cyclization reactions.
