The syntheses of the tricyclic ketoepoxides 1 and 2 from the readily available aromatic precursors 5 and 6 via cycloaddition of the spiroepoxycyclohexa-2,4-dienones 3 and 4 are described. The crystal structures of 1 and 2 were determined.
1-chloroalkynes and 1-bromohexyne undergo cycloaddition reactions with ethoxyvinylketeneiron(0) complexes to form chloro and bromocatechols. With most substituents, the halogen is incorporated ortho to the phenolic hydroxyl group regioselectively. With chloroethyne, chlorohexyne, and methyl chloropr
