Semmler–Wolff aromatisation: a concise route for the synthesis of 5-amino-quinazolines and 4-amino-indoles
摘要:
A simple and efficient methodology for the synthesis of 5-amino-quinazolines and 4-amino-indoles via Semmler-Wolff aromatisation reaction has been carried out. The oximation of keto intermediates followed by Semmler-Wolff aromatisation using acetic anhydride and a catalytic amount of sodium iodide in xylene provided the desired quinazolines and indoles.
