Abstract

The crystal and molecular structure of the title compound
was determined; its absolute configura CD spectral data. Crystals are orthorhombic, space group P212121
with : a= 15.857(4), b = 12.449(3), c = 6.120(2) A, U = 1208.11 A3,
Z = 4; De = 1.35 Mgm-s, μ(MoKa) = 0.25 mm-1• The final R = 0.048
for 671 observed reflexions [I> 3a (I)] . The conformation of the
dicnabicyclo (3.2.1] octane ring is boat-envelope-chair. Molecules
are connected in an infinite chain by hydrogen bonds between
N(3) amino and C(2) carbonyl groups [N - H ... 0, 2.881(8) A].
