The Michael Addition

A chiral M12L4 molecular tetrahedron (T) was synthesized by self-assembly of chiral cis-[(1S,2S)-dch]Pt(NO3)2 (M) with a hexadentate ligand (L) in 3 : 1 stoichiometric ratio. The cage T was found to catalyze the Michael addition reactions of series of nitrostyrene derivatives with indole in (9 : 1) water–methanol mixture.
