A highly efficient synthesis of sulphonamide derivatives in the presence of n-methyl-2-pyrrolidone

The sulphonamide derivatives are synthesized by two component condensation of alkyl bromide and sodium arylsulphonamide using N-methyl-2-pyrrolidone (NMP) as a reaction medium. This method results in high yields without the formation of unwanted side products, and expanding substrate scopes. Copyright

Linear and macrocyclic molecular thread, ribbon and belt assemblies of nanometric scale

The hitherto longest molecular thread-belt assemblies 8, 29, 32 and 43 based on benzene-connected [3.3]metacyclophane units were prepared by means of a repetitive synthetic method. The preparation of difunctionalized [3.3]metacyclophane units (14, 22, 26) succeeded in good yields by an iteration sequence including the cyclization to the cyclophane skeleton and the derivatization of the ester groups. The covalent linkage of the [3.3]metacyclophane belt parts to the thread part leads to higher product yields compared to cyclophane belts only. The final intermolecular macrocyclizations are done by reaction of diamide, dithiol or dibromide functionalized belt fragments to obtain a minimum of single bridged benzene units in the macrocyclic thread-belt assemblies ('pseudobelts').

Convenient synthesis of large tetraazamacrocycles bearing alkylene, cyclophane and crown ether type skeletons

A series of large tetraazamacrocycles with 28- to 44-membered rings consisting of alkylene, phenylene or ether type backbones has been prepared without the use of high-dilution conditions in practically significant yields (25-42%). The reaction can be car

Cupped Azacyclophanes Based on a m-Terphenyl Framework: Conformational Features of Their N-Tosylamide Precursors

Tetrabromomethyl m-terphenyl 4 was used to construct tetrakis-N-tosylamide cuppedophanes 8-10 and, by detosylation, the corresponding tetraazacuppedophanes 17-19.The para- and meta-bridged tosylamides 8 and 9 are conformationally rigid, but the ortho-brid

Chemistry of N-Nitrososulfonamides. Substitution Reaction by the Acetyl Group

The N-nitroso group on N-nitrososulfonamides was substituted for the acetyl group in chloroform to give N-acetylsulfonamides in moderate qields.
