(1R,3S,5R,6S)-6-Acet-oxy-8-methyl-3-(p-tolyl-sulfon-yloxy)-8-azoniabicyclo-[3.2.1]octane (2R,3R)-2,3-bis-(benzo-yloxy)-3-carboxy-propanoate

Rational design, synthesis and 2D-QSAR studies of antiproliferative tropane-based compounds

Novel tropane-based compounds were synthesized exhibiting antiproliferative properties against HepG2 and MCF7 carcinoma cell lines.

(1R,3S,5R,6S)-6-Hydr-oxy-3-tosyl-oxy-tropan-8-ium chloride

The title compound, C₁₅H₂₂NO₄S⁺·Cl⁻, is a hydrolysis product of lesatropane [(1R,3S,5R,6S)-6-acet­oxy-3-tosyl­oxytropane] hydro­chloride, a potential anti­glaucoma agent. As in lesatropane, the piperidine and pyrrolidine rings in the title compound adopt chair and envelope conformations, respectively. There are two mol­ecules in the unit cell with similar conformations. The crystal structure is stabilized by inter­molecular O—H⋯Cl and N—H⋯Cl hydrogen bonds.
