, p. 3873 - 3879 (2017/04/11)
A series of isomeric phenylphenalenones in which the phenyl ring is located at all possible peripheral positions of the phenalenone nuclei was synthesized. The structural characteristics of the series, in which topological variation is permitted with minimal electronic disturbance, could, in principle, allow for easy pharmacophore recognition when the compounds are aligned in steroidomimetic conformations.
Radical scavenging capacity of 2,4-dihydroxy-9-phenyl-1 H -phenalen-1-one: A functional group exclusion approach

2,4-Dihydroxy-9-phenyl-1H-phenalen-1-one (4-hydroxyanigorufone, 1), a compound isolated from Anigozanthos flavidus and Monochoria elata, displayed a high radical scavenging capacity in the ORAC assay. A systematic approach was adopted in order to explore
Synthesis of [phenyl-13C6]lachnanthocarpone and other 13C-labelled phenylphenalenones
Otalvaro, Felipe,Quinones, Winston,Echeverri, Fernando,Schneider, Bernd
, p. 147 - 159 (2007/10/03)
[phenyl-13C6]Lachnanthocarpone ([phenyl- 13C6]2,6-dihydroxy-9-phenylphenalen-1-one), a hypothetical intermediate in the biosynthesis of various natural phenylphenalenones, was prepared in four steps using [U- s
Synthesis of Haemofluorone B Trimethyl Ether
Feutrill, Geoffrey I.,Whitelaw, Murray L.
, p. 1523 - 1528 (2007/10/02)
The revision of the structure of haemofluorone B to 5,8,9-trihydroxy-3H-naphthoxanthen-3-one is confirmed by the synthesis of its trimethyl ether by photochemical oxidative cyclization of 9-(3,4-dimethoxyphenyl)-4-hydroxy-2-methoxy-1H-phenalen-1-one.The conventional process for conjugate arylation of phenalenones has been improved by the use of aryllithium reagents.
