Abstract
A new, conformationally rigid analogue of 2-aminoadipic
acid, 8-[(benzyloxy)carbonyl]-3-methylene-8-azabicyclo[3.2.1]octane-1,5-dicarboxylic
acid, is synthesized from dimethyl rac -2,5-dibromohexanedioate.
The key steps involve alkylation-cyclization of 1-benzyl
2,5-dimethyl pyrrolidine-1,2,5-tricarboxylate with 3-chloro-2-(chloromethyl)prop-1-ene
to yield the 8-azabicyclo[3.2.1]octane skeleton.
Key words
conformational restriction - bicyclic compounds - pyrrolidines - alkylations - cyclization

6 Three diastereomers of 4 : meso -, (2R ,5R )- and
(2S ,5S )- are formed
during the synthesis, each being suitable for alkylation. We chose
the crystalline (2R ,5R )-isomer 4 , which was easily separated from the
reaction mixture as it crystallizes upon standing in a fridge; the
product was filtered off and was washed with hexane. For the original procedure,

7 The configurations at C-2 and C-5 in
compounds 6 , 9 , 12a ,b , 14 and 15a ,b were not determined since they are lost
upon subsequent transformation into the non-chiral 8-azabicy-clo[3.2.1]octane
skeleton.

9 The conversion without addition of
HMPA was only 15% after 12 h at 20 ˚C. After 160
h, the transformation was complete; however, in the ¹ H
NMR spectrum of the crude mixture, together with 6 ,
a number of unidentified side products were detected. All subsequent
alkylations were performed in the presence of HMPA.
