概要
- 論文の詳細を見る
The title reaction is readily achieved with alkyl halides in the presence of sodium hydroxide and a phase transfer catalyst to afford 7-alkylated derivatives in good yields. The present reaction involving intramolecular double-alkylation at C-7 and N-6 with dihalides leads to novel fused heterocyclic systems.
