Cycloaddition of 1,4-Diaryl-1,3-butadiynes with Nitriles: An Atom-economic One-pot Approach to Benzo[f]quinazolines
A one-pot synthesis of benzo[f]quinazoline by a novel cycloaddition of 1,4-diaryl-1,3-butadiynes with nitriles in the presence of trifluoromethanesulfonic acid at 120 degrees C is developed.
