Regioselective Cyclization of Unsymmetrical Dicyanoanilines to Novel 2,3-BifuncIndole Regioisomers and Their Use in the Synthesis of 4,5-Dihy34- 157 tionalized
dro[1,3]oxazino[5,4-b]indole-6-carbonitriles. — The regioselective outcome is
strongly dependent on the nature of the substituent R1. The resulting indoles can
smoothly be converted into novel tricyclic oxazines such as (X) which are of biological
interest. — (MAITRAIE, D.; REDDY, G. V.; RAO, V. V. V. N. S. R.; RAVIKANTH,
