Synthesis of Methyl 2,6-Di-N-acetyl-2,3,4,6,7-pentadeoxy-l-lyxo-heptopyranoside, a Derivative of 6-epi-d-Purpurosamine B

Abstract
6-epi-d-Purpurosamine B, 2,6-diamino-2,3,4,6,7-pentadeoxy-l-lyxo-heptopyranose, was found to be a component of antibiotic fortimicins. Methyl 2,6-di-N-acetyl-6-epi-α-d-purpurosaminide B has been synthesized from methyl 2-acetamido-2-deoxy-6-O-trityl-α-d-glucopyranoside.
