[Pyrazino (1,2-a)- and 1,4-diazepino(1,2-a)indoles. II. Synthesis of 1-substituted 10-phenyl-3,4-dihydropyrazino(1,2-a)indoles and of 11-phenyl-4,5-dihydro-4H-diazepino(1,2-a)indoles]. 1975

F Gatta, and V Zaccari, and J P Huidobro-Toro, and S Chiavarelli

The AA. describe the synthesis of some 1-substituted 10-phenyl-3,4-dihydropyrazino(1,2-a)indoles and 11-phenyl-4,5-dihydro-3H-1,4-diazepino(1,2-a)indoles. Preliminary pharmacological tests indicate that these products, have lower sedative and antiadrenergic activity than the compounds reported in our previous paper.
