Stepwise Procedure

An efficient protocol for the synthesis of unsymmetrical aza[7]helicenes has been developed. The bis-styryl-type substrates for regiospecific photodehydrogenative oxidative double cyclization to give helicenes were prepared by a one-pot Wittig–Heck sequence as well as a stepwise procedure. The derivatives were characterized by single-crystal X-ray diffraction analysis and fluorescence spectroscopy.

An efficient and eco-friendly synthetic route for Friedländer quinoline synthesis of polysubstituted quinolines is described. This green chemical method starts from various 2-aminobenzophenones and mono- or dicarbonyl synthons and uses reusable Nafion NR50 material as a solid catalyst in ethanol under microwave irradiation. The protocol has a high generality of functional groups and provides the desired quinolines in good to excellent yields. Some structures were confirmed by single-crystal X-ray diffraction analysis.

AbstractA 2,2′-tert-butyl-5,9-6′,8′-cyclooctameric pyrenylene ([8]CP) was synthesized by a one-pot Suzuki–Miyaura cross-coupling reaction from two kinds of bifunctionalized monomers, as a rare example of a cyclic octamer. The octameric molecular structure of [8]CP was revealed by single-crystal X-ray diffraction analysis.

A series of chiral 10-heteroazatriquinanes were synthesized from enantiopure asymmetric cis-2,5-disubstituted pyrrolidines through a one-pot tandem cyclization procedure. The structures and configurations of these new chiral 10-heteroazatriquinanes are confirmed by X-ray single-crystal diffraction analysis.

Norbornene Derivatives

Here, we report a simple synthetic strategy to the bridgehead vicinal diallylation of norbornene derivatives. These substrates are useful to generate propellanes via ring-closing metathesis. Single-crystal X-ray diffraction analysis of four compounds led to the realization of configurational correction of earlier reported molecules.
