実験手順
For example, the protected aminotropane intermediate 16 can be prepared by reacting 2,5-dimethoxy tetrahydrofuran 17 with 1,3-acetonedicarboxylic acid 18 to provide 8-benzyl-8-azabicyclo[3.2.1]octan-3-one 19, commonly N-benzyltropanone. N-benzyltropanone is then reacted with a slight excess of di-tert-butyl dicarbonate in the presence of a transition metal catalyst to provide the protected Boc intermediate 20, which is reduced to provide the protected aminotropane intermediate 16.
