Novel Solid-State Synthesis of Dimeric 4-Aryl-1,4-dihydropyridines. -On irradiation in the solid state, 4-aryldihydropyridines (I) and (IV) undergo [2 + 2] cycloaddition to centrosymmetric head-to-tail dimers (II) and (V), respectively. Further irradiation of the dimers (II) provides the cage dimers

On irradiation at Ξ» Υ 270 nm solutions of 4-aryl-1,4-Irradiation with filtered light (Ξ» ΟΎ 313 nm) leads to syn and anti dimers 4 and 3 in nearly equal yields. The poor yields of dihydropyridines 1 yield cage dimers 2 as the main products beside small amounts of anti dimers 3. 1 H-NMR data and X-anti
