N. Yayli, ISOLATION AND CHARACTERIZATION OF AROMATIC SUBSTITUTED OLEFINIC COMPOUNDS FROM THE STARFISH PTERASTER-MILITARIS, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 33(6), 1994, pp. 556-561
Two series of the polyaromatic compounds (1-6 and 7-14) have been isol
ated from the starfish Pteraster militaris after column chromatography
over Amberlite XAD-2 resin. Their structures have been established by
spectroscopic means and confirmed as 2,4-diphenyl-1-butene (1), 4(p-e
thylphenyl), 2-phenyl-1-butene (2a), 2-(p-ethylphenyl)-4-phenyl-1-bute
ne (2b), 2,4-bis(p-ethylphenyl)-1-butene (3), 1,3-diphenyl-1-propanone
(4), 3-(p-ethylphenyl)-1-phenyl-1-propanone (5a), 1-(p-ethylphenyl)-3
-phenyl-1-propanone (5b), 1,3-bis(p-ethylphenyl)-1-propanone (6), 2,4,
6-triphenyl-1-hexene (7) and 2,4,6-triphenyl-1-hexanone (7d) by synthe
sis. Compounds 1 and 7 are known1 and have been synthesized by differe
nt route but the rest of the isolated and synthesized polyaromatic com
pounds are new.
