C-Glycosylations of several 2-naphthols with different glycosyl donors have been investigated in the pursuit of the total synthesis of mayamycin (1). While glycosylations of the parent 2-naphthol are readily achievable, those of 5-methoxy-7-methyl-2-napht

Methyl β-D-galactopyranoside was converted into methyl 4-azido-3-O-benzyl-6-O-t-butyldiphenylsilyl-2,4-dideoxy-β-D-arabino-hexoside, but subsequent transformation of the anomeric centre into a dithioacetal was unsatisfactory. Alternatively, methyl β-D-galactopyranoside easily gave methyl 4-azido-3,6-di-O-benzyl-2,4-dideoxy-β-D-arabino-hexoside, and this could be transformed by a reductive amination into two pyrrolidines as potential precursors to retronecine. Related chemistry gave (4S,5S,6R)-6-benzyloxy-4-benzyloxymethyl-3-oxa-1-azabicyclooctan-2-one, the structure of which was confirmed by a single-crystal X-ray structure determination. Finally, the synthesis of a potential precursor to heliotridine (an epimer of retronecine), namely methyl 4-azido-3-O-benzyl-6-O-t-butyldiphenylsilyl-2,4-dideoxy-α-D-ribo-hexoside, from methyl α-D-mannopyranoside is reported.
