title: Interconversion of the pallambins through photoinduced rearrangement.
abstract: A new photoinduced interconversion of four naturally occurring 19-nor-7,8-secolabdane diterpenoids was discovered and analyzed. The photochemical mechanism, intramolecular diradical rearrangement reaction, was investigated by time-lapse monitoring of the end product formations with HPLC and UV, as well as detailed theoretical calculations.
