Enantiopure phenylazomethine cages ((S)- and (R)-PAC) were selectively obtained by one-pot dehydration of chiral (S)- and (R)-syn-tris(norborneno) benzene with p-phenylenediamine in moderate yields (56% and 50%), respectively. The structure and chirality of PACs in solution and solid state were confirmed by NMR, CD, X-ray diffraction and DFT calculations.
