Meth­yl 2-amino-4-meth­yl-6-phen­yl-6H-1,3-thia­zine-5-carboxyl­ate

In the title compound, C₁₃H₁₄N₂O₂S, inter­molecular N—H...O(N) hydrogen bonds link the mol­ecules in the crystal structure into sheets parallel to the bc plane.

Methyl 4-(3-amino-2,4-dicyano-5,6,7,8-tetra­hydro­naphthalen-1-yl)benzoate

In the mol­ecule of the title compound, C₂₀H₁₇N₃O₂, the two benzene rings are nearly perpendicular, whereas the acetate group is slightly twisted with respect to the attached benzene ring. Inter­molecular N—H...N and N—H...O hydrogen bonds generate a zigzag chain which extends parallel to the b axis.
