Baillie, Lynn C.,Batsanov, Andrei,Bearder, John R.,Whiting, Donald A.
, p. 3471 - 3478 (1998)
The tricyclic amines (±)-2; R = H and R = Me with five stereogenic centres, representing the A/E/F ring system of the title alkaloids, have been synthesised from penta-1,4-dien-3-ol in eight (overall yield 20%) and nine steps (overall yield 16%) respectively.

The C53-C67 and C53-C65 polyene fragments of amphidinols have been synthesized in an efficient and convergent fashion from sorbic acid in good overall yields (30-31%) by employing a chemoselective cross-metathesis of a Weinreb amide and a Julia-Kocienski
Photochemistry of 2-Fluoro-2-alkylcyclohexanones. Drastic Effect of Fluorine Substitution
Reinholdt, Karin,Margaretha, Paul
, p. 119 - 122 (2007/10/02)
In the photreactions of 3-(2-oxocyclohexyl)-propionic acid derivatives 1 a pronounced effect of fluorine substitution is found on the ratio of a) Norrish II vs.Norrish I products; b) cyclization vs. cleavage of the Norrish II biradical; c) ketene vs. unsaturated aldehyde formation from the Norrish I biradical.
