                                    The synthesis of (5R,2'S,5'S,6'S)-ribosyl-diazepanone, an analogue core of liposidomycins is described. The core ribosyl seven-membered heterocycle of nucleoside antibiotic liposidomycins was formed by reductive amination of an alpha-ribosylamino ester derived from D-ribose, and an amino aldehyde derived from methyl 4-triisopropylsilyloxy-3-oxobutanoate, followed by a peptidic coupling reaction.
