Routes to 3aH-Indenes. Deprotonation and Methylation of some Indenones Bearing Ring Junction Substituents

The trienones (1), (2), and (3) have been converted into the corresponding enolate anions by reaction with potassium hydride below -10 deg C.Methyl fluorosulphonate was added to each solution: with the trienones (1) and (3), transient 3aH-indenes (4a) and
