Abstract: The tri-n-butyltin hydride-mediated reaction of methyl 3-O-allyl-4,6-di-O-benzyl-2-deoxy-2-(2-iodobenzoylamino)-alpha-D-glucopyranoside affords an unexpected benzomacrodilactam. The structure of this new 20-membered macrocyclic dilactam has been elucidated by electrospray mass and tandem mass spectrometry (ESI-MS/MS) and by H-1, C-13 NMR spectroscopy, COSY, TOCSY, HMQC and HMBC experiments.
