We have synthesized the title compounds having two pharmacophores of the β-phenethylamine moiety with a semi-rigid spatial arrangement. They are very suitable for studies on the limit of the effect of electron exchange between two aromatic chromophores.

building blocks in heteroannulation reactions with isatinimines. This convenient Mannich/cyclizationcascadereaction serves as a powerful tool for the enantioselectiveconstruction of bispirocyclic indanone–thioimidazolidine–oxindoles bearing two adjacent spiro-quaternary stereocenters in good to excellent yields with excellent diastereo- and enantioselectivities.
