Masschelein, Kurt G. R. published the artcileExploiting the regioselectivity of pyroglutamate alkylations for the synthesis of 6-azabicyclo[3.2.1]octanes and 4-azabicyclo[3.3.0]octanes, HPLC of Formula: 942603-91-0, the publication is Tetrahedron (2007), 63(22), 4712-4724, database is CAplus.
The preparation of 6-azabicyclo[3.2.1]octanes and 4-azabicyclo[3.3.0]octanes via regioselective alkylation and ring closure of pyroglutamates is described. Depending on the N-protecting group of pyroglutamates, the reactivity can be directed to the formation of 6-azabicyclo[3.2.1]octanes, e.g. I, or 4-azabicyclo[3.3.0]octanes, e,.g. II, which are conformationally restricted glutamate analogs. The stereoselectivity is also discussed.
