2-Benzyloxy-4-methoxy-2-cyclopentenone and 2-benzyloxy-2-cyclopentenone were efficiently prepared using furfuryl alcohol as the starting material. The synthetic route employed in both cases involves the previous preparation of a ketoaldehyde that is subsequently cyclized to the parent cyclopentenone. Each stage of this route involves reactions of very low cost, with simple synthetic procedures and very good yields.
Photoreactions of γ,δ-unsaturated chromium carbene complexes

A number of functionalized γ,δ-unsaturated chromium carbene complexes were synthesized, and their photochemistry was studied. Photolysis of carbene complexes 5 and 17 induced intramolecular [2 + 2] cycloaddition to afford cyclobutanones 6 and 18, respectively. If the photoreactions were not run in thoroughly degassed solvents, small amounts of lactones 7 and 19 were obtained as well. Cyclobutanones 6 and 18 were stable once isolated, but underwent an acid-catalyzed Pinacol rearrangement/hydrolysis transformation in acidic solution to afford novel α-hydroxy-substituted bicyclo[3.1.0]hexanone compounds 20 and 21. Photolysis of cyclopropyl carbene complex 28 induced a vinylcyclopropyl rearrangement involving the photogenerated ketene moiety to provide α-alkoxy cyclopentenone 29.
