5-aryl-N,N-dimethyl-6-nitro-2-cyclohexen-1-amines 7. Reduction of 7 with zinc in acetic acid gave the diamino derivatives 8. Schotten-Baumann acylation of 8 gave amides 9. Treatment of 8 with alkylisocyanates gave the aminourea derivatives 10. Bischler-Napieralski cyclodehydration procudure of 9 and 10 gave 1,4,4a,10b-tetrahydrophenanthridinamines 3 and N6-alkyl-1,4,4a,10b-tetrahydro-N4,N4-dimethyl-4
