Heterocyclic Photochemistry in Contrast with Carbon Behavior. Regioselective Photochemical Rearrangement of an Azacyclohexadienone: Mechanistic and Exploratory Organic Photochemistry

Autor: Howard E. Zimmerman, S. V. Shorunov

Publikováno v: The Journal of Organic Chemistry. 74:5411-5416

The Type-A photochemistry of cyclohexadienones is well-studied and follows a well-established mechanistic pathway. One early example is the rearrangement of santonin to lumisantonin. Another example is the rearrangement of 4,4-diphenylcyclohexa-1,5-d

Synthesis of novel amides derived from lumisantonin

Autor: Fernanda C. Moraes, Kariny B. Amorim, Elson S. Alvarenga

Publikováno v: Proceedings of the 15th Brazilian Meeting on Organic Synthesis Proceedings.

Sesquiterpene lactones are present in many medicinal natural sources and exhibit a variety of biological activities 1 . As part of our current synthetic programme related to natural sesquiterpenes with biological activity, we have synthesized a serie

Pharmacological studies of lumisantonin derivatives, with special reference to anti-inflammatory effect and to histamine-release inhibitory action

Autor: Takashi Yamamoto, Kazuji Kondo, Hidemasa Yamasakl, Teruo Uda, Koiti Endo

Publikováno v: Acta Medicinae Okayama. 15(6):347-366

A number of derivatives and related compounds of lumisantonin were submitted to evaluatien for the action of histamine-release inhibition and antiinflammatory effect, as they structurally resemble guaiazulene in which these actions had been proved. N

Photochemische Reaktionen. 18. Mitteilung. Die Konstitution der Photosantoninsäure

Autor: D. Arigoni, O. Jeger, E. Schott

Publikováno v: Helvetica Chimica Acta. 46:307-319

On the basis of degradative work and spectroscopic evidence structure 3 has been derived for photosantoninic acid, a dimeric compound previously obtained by the action of UV.-light on alcaline solutions of santonin (1). The stereochemistry of the com
