On ?,?^*-excitation of the epoxyenone (E)-1 (λ = 254 nm, MeCN), in addition to the previously isolated compounds 2-9, the new products 10-12 derived from the ylide intermediate c were isolated.Further evidence for the ylide c was obtained by the rapid racemization of the optically active epoxyenone (-)-(E)-1.
