摘要：
An unexpected rearrangement aromatization of benzo[c]oxepine has been revealed to synthesize substituted naphthalenes. This observation was further exploited to develop an efficient approach for the construction of naphthalenes from simple and commercially available 1,3-dicarbonyl compounds and 1,2-bis(halomethyl)benzene compounds via a new domino reaction sequence.

摘要：
Eight unsymmetrical N and/or O-bridged calixarene derivatives were obtained by 1 (naphthalene-2,7-diol), 2 (bis(4-hydroxyphenyl)methanone), 3 (4,4′-methylenedianiline), 4 (3,3′-methylenedianiline), 5 (4,4′-oxydianiline) and 6 (4,4′-(perfluoropropane-2,2-diyl)dianiline) reacting with fragment a (4,4′-bis(dichloro-s-triazinyloxy)propane-2,2-diyldibenzene) and b (N,N′-bis(dichloro-s-triazinyl)-4,4′-methylenedianiline) under very mild reaction conditions via efficient fragment coupling strategy. We also obtained the crystal structure of 1a (tetraoxocalix[2](propane-2,2-diyldibenzene,naphthalene)[2]triazine) which can form a molecular capsule by two dimers with C–H⋯N and C–H⋯O quadruple hydrogen bonds, and it has the encapsulation ability toward solvent molecules.

摘要：
Secondary or tertiary amides have been prepared directly from aryl, heteroaryl methyl ketones using an iodine– amine–NaOH system which afforded the expected products in good yields in an aqueous medium. The present method has the advantages of using inexpensive reagents, mild reaction condition and ease of manipulation.

摘要：
We report herein a five-component self-sorted system comprising molecular clips that form heterodimers 1.4 and 8.11, and homodimer 14.14 in C(6)D(5)CD(3)/CDCl(3). The three component self-sorting mixture comprising 1.1, 8.8, and 14.14 undergoes triggered reassembly self-sorting upon addition of 4.4 and 11.11.

摘要：
A novel glycoluril molecular clip has been designed, synthesised and characterised. The X-ray crystallographic analysis revealed that the molecular clip had a large enough cavity to show the capability of encapsulate DMSO molecule. The supramolecular structure formed via N-H center dot center dot center dot O and pi-pi interactions, the molecules were linked into a two-dimensional structure.

摘要：
A highly efficient synthesis of hydantoins has been developed from simple and commercially available 1,3-dicarbonyl compounds, ureas, and methyl ketones or terminal aryl alkenes. This protocol involves a sustainable integration of two coupled domino processes: iodine-promoted synthesis of unsymmetrical 1,4-enediones (domino I) and the sequential transformation into hydantoins (domino II).

摘要：
A highly efficient synthesis of unsymmetrical 1,4-enediones from 1,3-dicarbonyl compounds and methyl ketones or terminal aryl alkenes has been developed via a focusing domino strategy. Simple and readily available starting materials, mild reaction conditions, and a very simple operation are advantages of the reaction, which allow straightforward synthesis of a variety of unsymmetrical 1,4-enediones.
