In the title compound, C(19)H(21)NO(4), an organocatalyst with a tetra-hydro-isoquinoline backbone, the heterocyclic ring assumes a half-boat conformation. The dihedral angle between the aromatic rings is 82.93 (8)°. In the crystal, mol-ecules are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a layer parallel to (10[Formula: see text]).

The tetra-hydro-quinazoline fused-ring system of the title compound, C(11)H(10)N(2)OS, is approximately planar (r.m.s. deviation = 0.019 Å). In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds, forming a chain running along the b axis.

In the title compound, C19H16N4O3, the stereocenter has an l configuration; l-tryptophan methyl ester hydro-chloride being used as a starting material. The indole ring system and the pyridine ring are inclined to one another by 13.55 (14)°. In the crystal, adjacent mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains propagating along the c-axis direction.

In the title compound, C14H14INO4, the di-hydro-pyridine ring adopts a twist conformation. In the crystal, pairs of N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into inversion R 2 (2)(10) and R 2 (2)(18) dimers, forming infinite double chains running along the c axis.

Electromagnetic forming is a high energy rate forming process in which an electromagnetic Lorentz body force is used for deformation of products.  In this article, electromagnetic forming process was simulated for the assembly of parts as an innovative method.  The effect of important process parameters such as discharge energy, radius and width of rectangular groove on the strength of the asse...
