Photochemistry of 2-Fluoro-2-alkylcyclohexanones. Drastic Effect of Fluorine Substitution

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.

SYNTHESIS OF 9-HEXADECEN-15-OLIDES; HYPOTHETICAL INTERMEDIATES IN THE BIOSYNTHESIS OF BREFELDIN A

Four types of lactones 1-4 which might be biosynthetic intermediates of brefeldin A have been synthesized.In the course of their synthesis, it was found that coupling of a hydroxy phosphonium salt and a carbomethoxy-aldehyde gave a macrocyclic lactone in
