Studies on novel synthetic methodologies, part XII: An efficient one-pot access to 6,6a-dihydroisoindolo[2,1-a]quinazoline-5,11-diones and 5-phenylisoindolo[2,1-a]quinazolin-11(6a H)-ones

Sashidhara, Koneni V.,Palnati, Gopala Reddy,Dodda, Ranga Prasad,Avula, Srinivasa Rao,Swami, Priyanka

, p. 105 - 113 (2013)

A simple and efficient procedure for the construction of 6,6a-dihydroisoindolo[2,1-a]quinazoline-5,11-dione and 5-phenylisoindolo[2,1-a] quinazolin-11(6aH)-one derivatives in acetic acid under catalyst-free conditions is described. Attractive features of this methodology are its versatility, ready availability of starting materials and the efficiency in creating a complex core in a single operation.
