Synthesis of the glucoallosamidin pseudo-disaccharide: Use of an efficient Hg(II) mediated cyclization
Shrader, William D.,Imperiali, Barbara
, p. 599 - 602 (1996)
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
