Total synthesis of (+)-FR-900493 and establishment of its absolute stereochemistry

The first total synthesis of (+)-FR-900493, an antibacterial nucleoside antibiotic possessing a 6′-N-alkyl-5′-O-aminoribosyl-glycyluridine structure, is described, and its relative and absolute stereochemistries were established. Key elements of the appro
