[structure: see text] Carboxamides possessing naphthalene rings connected by multiple iminodicarbonyl linkers were synthesized. These molecules forced the naphthalene rings to be placed in the positions facing each other, and they form helical foldam

The photocycloaddition reaction of naphthyl-N-(naphthylcarbonyl)carboxamides (1) was examined under argon and oxygen atmospheres. In addition to the [2 + 2] and [4 + 4] cycloadducts, 3 and 4, respectively, novel 1,8-epidioxides (5) were formed under

A novel clathrate host, N,N‘-bis(2-tert-butylphenyl)pyromellitic diimide (1), was designed to create a sandwich structure without using cyclophanes nor the acyclic compounds. In the host−guest crystal, the host molecule is sandwiched between two

The first tandem radical cyclization of linear homoallylic xanthates was explored. Homoallylic santhates prepared from α,β-unsaturated esters were easily cyclized by tin hydride with an radical initiator to give the corresponding thionolactone annu

Conformational control of a cyclophane with intermolecular hydrogen bonding was accomplished through the first synthesis of a carbamoyloxa-bridged cyclophane 3, with the result that the crystal structures of two isolable conformers 3a and 3b were elu
