“…Stilbenes-or 1,2-diphenylethylenes, of which more than 300 are known-are biologically active compounds that have shown different activities, such as nitric oxide production inhibition and antibacterial, antifungal, antioxidant, anti-inflammatory, anticancer, and antimalarial activities (123)(124)(125)(126)(127)(128). These compounds and/or their glycosides also have attracted much attention for their biological effects, including antioxidant cyclooxygenase-I and -II inhibitory (129), antiplatelet-aggregation (130), antifungal (131), tyrosinase-inhibitory (132), anti-HIV-1, and cytotoxic effects (133), which play an important role in photochemical reactions (134,135). They have been found in many families of higher plants but mainly in Vitaceae, Gnetaceae, Polygonaceae, Liliaceae, Moraceae, and Cyperaceae.…”

This review article presents 342 aromatic glycosides, isolated from and identified in plants and microorganisms, that demonstrate different biological activities. They are of great interest, especially for the medicinal and/or pharmaceutical industries. These biologically active natural surfactants are good prospects for the future chemical preparation of compounds useful as antioxidant, anticancer, antimicrobial, and antibacterial agents. These glycosidic compounds have been classified into several groups, including simple aromatic compounds, stilbenes, phenylethanoids, phenylpropanoids, naphthalene derivatives, and anthracene derivatives.

“…The reaction was thoroughly reviewed by Mallory in a large chapter in Organic Reactions in 1984 [ 5 ]. Other reviews [ 6 , 7 , 8 , 9 , 10 ] discuss various aspects and applications of the reaction. This review will focus on the reaction as a useful tool in synthesis, covering developments reported since 1984.…”

Photochemical Oxidative Cyclisation of Stilbenes and Stilbenoids—The Mallory-Reaction

2010

View full text Add to dashboard Cite

After Mallory described in 1964 the use of iodine as catalyst for the photochemical cyclisation of stilbenes, this reaction has proven its effectiveness in the synthesis of phenanthrenes, other PAHs and phenacenes with a surprisingly large selection of substituents. The “early age” of the reaction was reviewed by Mallory in 1984in a huge chapter in the Organic Reactions series, but the development has continued. Alternative conditions accommodate more sensitive substituents, and isomers can be favoured by sacrificial substituents. Herein the further developments and applications of this reaction after 1984 are discussed and summarized.

“…Polycyclic aromatic hydrocarbons (PAHs) have long been recognized as a pivotal class of compounds in the field of organic chemistry, and after the rise of graphene, the renewed and widespread attention to nanosized graphenes, or extended PAHs, accelerates the precise synthesis and characterization of structurally well-defined graphene fragments . Among a wide variety of PAH molecules, derivatives of hexa- peri -hexabenzocoronene (HBC), or so-called “superbenzene”, are of great interest because of their similarity to the corresponding benzene derivatives and their application in organic electronics .…”

Luminescent Superbenzene with Diarylamino and Diarylboryl Groups

2017

Dianisylamino donor and dimesitylboryl acceptor substituents were introduced at the 2,11-positions of hexa-peri-hexabonzocoronene (HBC) to demonstrate an effective fluorescent enhancement of HBC as virtually nonfluorescent "superbenzene". The present donor-acceptor substitution replaced the typical weak α-band with an intense intramolecular charge-transfer band in the absorption spectrum, thereby leading to a much larger fluorescence quantum yield (Φ = 0.56 in CHCl) than any other HBC derivatives.
