1-(Methylamino)anthracene – An Accessible Building Block for Photoresponsive Compounds
Ulatowski, Filip,Melaniuk, Karolina
, p. 6629 - 6633 (2018/11/23)
In this paper we present a convenient and scalable synthesis of 1-(methylamino)anthracene, which is a potent building block for the construction of photoresponsive materials. With this structural motif we have synthesized an anion receptor bearing two anthracene groups. Interaction of a chloride anion with the anthracene moieties increases the association constant. Photocycloaddition allows to obtain a single macrocyclic receptor, which exhibits higher binding constants due to the macrocyclic effect.

Mechanism for photocleavage of N-(anthroyloxy)-9-fluorenylideneamines and dynamic behavior of anthroyloxyl radicals

, p. 2013 - 2023 (2007/10/03)
Photocleavage of the N-O bond of N-(9-anthroyloxy)-9-fluorenylideneamine and its 1-and 2-anthroyloxy derivatives takes place efficiently in acetonitrile in the excited singlet state attributed to the fluorenylidene moiety. This made it possible for the first time to directly observe anthroyloxyl radicals by the transient absorption method. The quantum efficiency for photocleavage decreases remarkably in benzene, in which the lowest excited singlet state is attributed to the anthroate moiety. All the three kinds of anthroyloxyl radicals are much less reactive in decarboxylation, addition to olefins, and hydrogen-atom abstraction than benzoyloxyl and 1- and 2-naphthoyloxyl radicals; 9-anthroyloxyl radicals supposedly undergo intramolecular addition-elimination in the ipso-position in equilibrium with α-lactonic spirodihydroanthryl radicals, as indicated by one-color and two-color laser photolyses.
Synthesis, DNA-damaging and cytotoxic properties of novel topoisomerase II-directed bisantrene analogues
Zagotto, Giuseppe,Oliva, Ambrogio,Guano, Fulvio,Menta, Ernesto,Capranico, Giovanni,Palumbo, Manlio
, p. 121 - 126 (2007/10/03)
New bisantrene analogues were synthesized, bearing one or two 4,5-dihydro-1H-imidazol-2-yl hydrazone side chains at positions 1,4 or 9 of the anthracene ring system. A 10-aza-bioisostere was also prepared. The position of substituents in structurally isomeric drugs modulates topoisomerase II poisoning and specificity, along with cytotoxicity.
Photoisomerization and Photocyclization Reactions of 1-Styrylanthracene
Karatsu, Takashi,Kitamura, Akihide,Zeng, Hualing,Arai, Tatsuo,Sakuragi, Hirochika,Tokumaru, Katsumi
, p. 920 - 928 (2007/10/02)
On triplet sensitization, 1-styrylanthracene (1SA) undergoes adiabatic cis->trans one-way isomerization (3c*->3t*) similarly to 2-anthrylethylenes.However, upon direct irradiation, cis-1SA in the singlet excited state mostly undergoes cyclization to a dihydrophenanthrene-type product (DHP), 4a,4b-dihydrobenzochrysene, competing with an inefficient intersystem crossing to 3c* followed by one-way isomerization.The produced DHP, in deaerated benzene, is reverted to cis-1SA by a thermal (Ea = 14.9 kcal mol-1) or a photochemical pathway; however, under an oxygenated atmosphere DHP gives benzochrysene.A failure in the production of a cyclized product upon the excitation of trans-1SA shows that the isomerization really takes place in a one-way fashion.
