1,1-Bis(4-fluorophenyl)-3,4-dihydro-1H-1,3-oxazino[3,4-a]indole

1,1-Bis(4-fluorophenyl)-3,4-dihydro-1H-1,3-oxazino[3,4-a]indole

The title compound, C23H17F2NO, which crystallizes with two independent molecules in the asymmetric unit, was prepared by the cyclization of 4-[2-bis(4-fluorophenyl)methyleneamino]but-3-yn-1-ol at room temperature. The molecules display a tripod conformation. The two fluorophenyl rings make dihedral...
