The totalsynthesis of the cytotoxin fasicularin is described. The key steps include the following: (1) an intermolecular Diels-Alder cycloaddition of a 2-(triflamido)acrolein with the dioxolane ketal of trideca-1,3-dien-7-one to establish the trans-perhydroisoquinoline stereochemistry, (2) a stereoelectronically controlled hydride addition to a N(1)-C(2) iminium ion to introduce the equatorial hexyl

In the photoreactions of 3-(2-oxocyclohexyl)-propionicacid derivatives 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.
