In a similar manner to that described for bicyclic lactams (Section 1.1.1.3.3.4.1.5.I.). alkylation reactions of tricyclic lactams, which contain a fused benzene ring adjacent to the carbon undergoing alkylation, have been exploited14. The first alkylation of the benzo-annulated bicyclic lactam 1 gives a mixture of diastereomers, which is then further alkylated. In the second alkylation step, the counterion on the alkoxide, which is formed prior to enolate formation, proved to be crucial for the diastereoselectivity of the subsequent alkylation reaction. The best diastcrcoselectivity was obtained when either dichlorobis(ij5-cyclopentadienyl)zirconium or triisopropoxytitanium chloride was added to the preformed alkoxide, followed by enolization and alkylation. Using this method the second alkylation step gives a satisfactory diastereoselectivity. Hydride reduction of the purified major diastereomer 2, followed by acid treatment of the product, furnishes chiral naphthalenones 414.

Treatment of 1-azirine (292) with catalytic quantities of dichlorobis(benzonitrile)pal-ladium(II) gave a quantitative yield of the indole (293) (77CC664). This transformation proceeds through the intermediacy of a 2 1 azirine-palladium chloride complex. Conversion of the 1-azirine ring to indoles under uncatalyzed thermolytic conditions provides a mechanistically interesting comparison with the Pd(II)-catalyzed conversions. The C—N bond cleavage in the latter is apparently accelerated as a result of the coordination of the azirine to palladium.
