Synthesis and Sulfur Electrophilicity of the Nuphar Thiaspirane Pharmacophore

open access: yes, 2016
We describe a general method to synthesize the iminium tetrahydrothiophene embedded in the dimeric Nuphar alkaloids. In contrast to prior studies, the sulfur atom of the thiaspirane pharmacophore is shown to be electrophilic. This α-thioether reacts with
