It was found that the reactions of arylamines with 3-bromocyclohexene afforded hydrocarbazole compounds in 64--78% yields. A modified procedure for the synthesis of antitumor alkaloid ellipticine was proposed.

A Facile Method for the Synthesis of 3,1-Benzoxazines from N-Acyl-2-(alk-2-enyl)anilines.-Electrophilic addition of HCl or Br 2 to N-acylated o-alkenylanilines proceeds with oxazine ring closure to furnish the spirocyclic benzoxazines in excellent yields, irrespective of geometry or substitution pattern around the double bond.-(GATAULLIN, R.
