Syntheses of 1,6-dideoxy-1,6-imino-D-mannitol (D-mannoazepane) (1) and 1,6-dideoxy-1,6-imino-D-glucitol (D-glucoazepane) (3) from D-isoascorbic acid and D-glucono-1,5-lactone, respectively, are described. The key step in both routes involved reductive aminative 1,6-cyclization with retention of configurations to give the corresponding lactams, which were subsequently reduced to afford compounds 1 and 3 in 24 and 28.5%, overall yield, respectively.
