Vinylketenes (generated in situ from cyclobutenones or a-diazo ketones) react with ynamides via a pericyclic cascade process to produce highly-substituted aniline derivatives. Cyclization of the benzannulation products can then be achieved via several alternate procedures leading to indoles that are highly substituted on the six-membered ring. The cyclization approaches investigated as the second step in this tandem strategy included aromatic substitution, palladium-catalyzed oxidative amination, and nucleophilic cyclization. This thesis discusses the scope and limitations of this tandem strategy.

A tandem benzannulation-cyclization strategy was successfully applied to the synthesis of a tetracyclic heteroaromatic compound expected to have interesting electronic properties. Benzannulation of a diazo ketone and a ynamide yielded a highly substituted aniline that was cyclized to indole according to protocols developed in our laboratory previously.

Benzannulations employing ynamides and vinylketenes (generated in situ from [alpha]-diazo ketones) were investigated. Irradiation of the diazo ketones using a batch or continuous-flow reactor leads to the formation of vinylketenes via a photo-Wolff rearrangement. The vinylketenes then react with ynamides via a pericyclic cascade process to produce highly substituted aniline derivatives. Using this vinylketene-based benzannulation, tandem strategies for the synthesis of highly substituted benzo-fused nitrogen heterocycles were investigated. A tandem benzannulation-iodocyclization method for the synthesis of polysubstituted quinolines was established. In addition, a tandem strategy for the synthesis of carbazoles was developed and applied in the total synthesis of the carbazole alkaloid carazostatin as well as formal syntheses of the alkaloids carbazoquinocin C and antiostatin A₄.

Повний текст джерелаThe ring-opened adduct was also envisaged as a potential substrate in intramolecular Heck reactions. To this end, Heck substrates were generated from the ring-opened adduct anion and iodo- and bromo-benzyl halides. A key observation at this stage pertained to the unexpected acidity of the ring-opened adduct C5 proton, which could be deprotonated by DBU to bring about allylic isomerization, a finding that would provide a key insight to the pattern of reactivity later evidenced with alkyl propiolates. Optimization of the Heck substrate-generating reaction was followed by Heck reactions under Jeffery's conditions, which generated angular tricycles as intended, accompanied by aromatic compounds generated by base-induced HCN elimination/rearrangement and dehydrogenation. The Jeffery's conditions were optimized to limit the production of aromatics.
The possibility of ring-opened adduct-derived vinyl silane intermediates undergoing cationic cyclizations led to a minor study based upon the bromination of allylsilanes and the elimination of TMSBr from 1,2-dibromo-3-trimethylsilyl compounds, accessible compounds unaccounted for in the review literature. It was determined that the combination of HBr and Br2 (perhaps as HBr3) was required to eliminate TMSBr, in contravention of the textbook account of electrophilic substitutions being the inherent reactions of allylsilanes and Br2.
Unexpected tandem reactivity was observed in the reactions of the anionic ring-opened adduct and alkyl propiolates under catalytic DBU conditions. Rather than tandem cyclization or simple adduct formation, the allenolate intermediates were determined to undergo extremely facile formal allenolate Cope rearrangements involving the ?,d-double-bond of the parent ring. Excess base intercepted the allenolate by deprotonating ring C5 and effecting 1,2-vinyl transfer by 3-exo-trig addition-elimination. The chemistry of the highly delocalized side-chain carbanion in the Cope product was studied in detail.
