Summary
The treatment of a mixture of linearly and angularly annelated 2-substituted oxazolo[4,5-f]quinolones (5a–c) and oxazolo[5,4-g]quinolones (6a–c) and similarly the treatment of 2-substituted oxazolo[5,4-f]quinolones (7a–c) and oxazolo[4,5-g]quinolones (8b,c) with POCl3 afforded substituted 4-chlorooxazolo[4,5-f]quinolines (9a–c) and 2-substituted 4-chlorooxazolo[5,4-f]quinolines (10b,c), respectively. Spectral characteristics of the synthesized derivatives (1H and13C NMR, IR, UV, and MS) are discussed.
Zusammenfassung
Durch Umsetzung einer Mischung von linear und angulär anellierten 2-substituierten Oxazolo[4,5-f]chinolonen (5a–c) und Oxazolo[5,4-g]chinolonen (6a–c) mit POCl3 beziehungsweise durch analoges Behandeln von 2-substituierten Oxazolo[5,4-f]chinolonen (7a–c) und Oxazolo[4,5-g]chinolonen (8b,c) erhält man substituierte 4-Chlor-oxazolo[4,5-f]chinoline (9a–c) bzw. 4-Chlor-oxazolo[5,4-f]chinoline (10b,c). Die spektroskopischen Eigenschaften der Verbindungen werden diskutiert (1H- und13C-NMR, IR, UV, MS).
