Article abstract of DOI:10.1016/0040-4039(95)02230-9

The title compound 1a was prepared from cyclopentadienylthallium in 11 steps. The key component of the pseudo-disaccharide 1a, (-)-allosamizoline 2, was synthesized in 2 steps starting from the known cyclopentene 4 by formation of the aminoimidate 5 follo
