Reaction Steps

Analogously to Step F, 11 g of crude methyl (1S,6R)-1-methoxycarbonylamino-8-azabicyclo[4.3.0]nona-2,4-diene-8-carboxylate are hydrolysed in 150 ml of water using 42 g of Ba(OH)2.8 H2O and worked up accordingly. Yield: 3 g (44.6% of theory based on Step G), boiling point: 70° C./0.1 mbar, [α]D =+235.9° (c=1,14, methanol).
