Novel benzoxazino quinoline derivatives of Formula (I) and benzoxazino isoquinoline derivatives of Formula (II) are provided:
Also provided is a transition-metal-free multicomponent reaction of arynes, N-heterocycles, and carbonyl compounds leading to the diastereoselective synthesis of benzoxazino quinoline derivatives of Formula (I) and benzoxazino isoquinoline derivatives of formula (II) in good yields proceeding via 1,4-zwitterionic intermediates. The compounds possess anti-malarial activity.

The multicomponentreaction involving arynes, quinolines, and aldehydes leading to the diastereoselective synthesis of benzoxazino quinoline derivatives in good yields proceeding via 1,4-zwitterionic intermediates is reported. In addition, the synthetic potential of various carbonyl compounds in this reaction as well as the utility of isoquinoline as the nucleophilic trigger has been examined.
