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.
Enamides were efficiently prepared via a novel Rh/C-catalyzed direct hydroacylation of ketoximes. Up to 88% isolated yield of enamides were obtained with this method. Subsequent asymmetric hydrogenation of the enamides with Rh/DuanPhos complex gave the corresponding chiral amine in excellent enantioselectivities (up to 99.7% ee).

This report describes the diverse dimeric products obtained by treatment of N-acylindan-1-amines with ethyl polyphosphate in chloroform–diethyl ether solution at 80 °C for 8 h. Possible mechanisms for such reactions are discussed.
