Cyclized product 4bb was obtained without further addition of any reagents or additives after carrying out the mesylation. An additional allyl group can be installed onto the nitrogen atom, which, following metathesis, can provide piperidines (4cb) in good yields. Finally, the allyl group is amenable to Friedel-Crafts type chemistry by using a biphasic system consisting of chloroform and sulfuric acid. Attempting this transformation using neat sulfuric acid resulted in precipitation of the starting material, which necessitated using a co-solvent. The electron rich aniline ring can be used to access tetrahydroquinolines (4da), that can undergo subsequent oxidation with DDQ or activated manganese dioxide to quinolines (4db). The products of the Friedel-Crafts reaction were observed in a 5:1 diastereomeric ratio. It is worth noting that all yields for the reactions in Scheme 2 are unoptimized, yet they demonstrate that an array of heterocycles are indeed accessible directly from the homoallylic amine precursors.
