| titleOfInvention | A method of efficiently preparing quinazolinones |
| abstract | The invention discloses a kind of methods efficiently preparing quinazolinones, using 3 oxygen quinazolines and aldehyde as substrate, mantoquita is as catalyst, the tert-butyl hydroperoxide of 5.5M in decane is oxidant, quinazolinones are obtained by the reaction at nitrogen atmosphere and 40 DEG C, its reaction equation is (1), the present invention realizes the single step reaction using 3 oxygen quinazolines and aldehyde, more directly succinct synthesis quianzolinones, reaction is more directly succinct, substrate limitation is small, and reaction temperature is low, the time is short, its potential using value is better achieved. |
