Synthetic approaches to bowl-shaped π-conjugated sumanene and its congeners
Beilstein J. Org. Chem. 2020, 16, 2212–2259, doi:10.3762/bjoc.16.186
- ’ “Suman”, which means “Sunflower”), a beautifully simple yet much effective bowl-shaped C3-symmetric polycyclic aromatic hydrocarbon having three benzylic positions clipped between three phenyl rings in the triphenylene framework has attracted a tremendous attention of researchers worldwide. Therefore
Six-fold C–H borylation of hexa-peri-hexabenzocoronene
Beilstein J. Org. Chem. 2020, 16, 391–397, doi:10.3762/bjoc.16.37
- , Nagoya, 464-8602, Japan 10.3762/bjoc.16.37 Abstract Hexa-peri-hexabenzocoronene (HBC) is known to be a poorly soluble polycyclic aromatic hydrocarbon for which direct functionalization methods have been very limited. Herein, the synthesis of hexaborylated HBC from unsubstituted HBC is described. Iridium

Facile synthesis of 4H-chromene derivatives via base-mediated annulation of ortho-hydroxychalcones and 2-bromoallyl sulfones
Beilstein J. Org. Chem. 2016, 12, 16–21, doi:10.3762/bjoc.12.3
- . Polycyclic aromatic hydrocarbon frameworks (naphthalene and anthracene rings) as well as a representative heterocyclic ring (furan) may be incorporated into the 4H-chromene skeleton product by using chalcones (7c, 7d, and 7e, respectively) functionalized with these moieties. Disappointingly, attempts to
Aryl substitution of pentacenes
