Chemical Constituents of Piper betle Linn. (Piperaceae) Roots

open access: yesMolecules, 2005
Column chromatography of the alcoholic extract of Piper betle roots furnished aristololactam A-II and a new phenyl propene, characterized as 4-allyl resorcinol, while the petroleum-ether extract yielded a diketosteroid, viz. stigmast-4-en-3,6-dione.

Some sigmatropic rearrangements of polyfluoroaromatic and heteroaromatic compounds [PDF]

open access: yes, 1986
This Thesis describes some [3,3] and [2,3] -sigmatropic rearrangements that can occur in a variety of polyfluoroaromatic and -heteroaromatic compounds. The presence of fluorine on the aromatic moiety precludes the normal rearomatization process. The
