Providing high quality automotive electronics with low power consumption and high operating performance requires excellent engineering methodology using the most accurate models (APL, CMM, .libs etc). Dynamic voltage drop affects power, timing and reliability of a design. In order to see the correct hot spots and decide on the appropriate counter measures(More)
In the title compound, C(34)H(32)N(2)O(8), one of the pyrrolidine rings in the pyrrolizidine ring system adopts a twist conformation, whereas the other ring adopts an envelope conformation (C atom as flap). The five-membered ring in the indene ring system and the fused furan ring also adopt envelope conformations (C and O atoms as flaps, respectively). The(More)
In the title compound, C(28)H(27)NO(5)S, the five-membered pyrrolidine ring, which exhibits an envelope conformation (the C atom at the spiral junction being the flap atom), makes dihedral angles of 57.37 (10) and 86.84 (8)°, respectively, with the phenyl ring and the acenaphthyl-ene ring system. In the crystal, mol-ecules associate via two C-H⋯O hydrogen(More)
In the mol-ecule of the title compound, C(19)H(17)NO(3)S, the dihedral angle formed by the quinoline ring system and the thio-phene ring is 83.15 (8)°. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into a C(8) chain running along the b axis. The packing of the mol-ecules is further influenced by C-H⋯π inter-actions.
In the title compound, C(28)H(26)N(4)O(4), the tetra-hydro-pyridine ring adopts a boat conformation. The two phenyl rings form dihedral angles of 88.64 (8) and 59.28 (10)° with the best plane through the tetra-hydro-pyridine ring. The dihedral angle between the two phenyl rings is 82.55 (10)°. The benzotriazole ring system is essentially planar, with a(More)
In the title compound, C(18)H(22)ClNO(5), the cyclo-hexene ring adopts a distorted half-chair conformation. The mol-ecular structure is stabilized by pairs of intra-molecular N-H⋯O and O-H⋯O inter-actions, generating S(6) motifs. In the crystal, the mol-ecules are linked by inter-molecular C-H⋯O inter-actions, forming centrosymmetric dimers.
In the title compound, C(29)H(26)N(2)O(5)S, the piperidine ring adopts a half-chair conformation. The phenyl rings are oriented at dihedral angles of 75.76 (12) and 86.64 (9)° with respect to the best plane through the piperidine ring. The dihedral angle between the two phenyl rings is 30.81 (13)°. The benzoxazole ring system is approximately planar(More)
In the title compound, C(27)H(25)NO(4), the tetra-hydro-pyridine ring adopts a half-chair conformation. The three phenyl rings form dihedral angles of 66.33 (7), 87.36 (8) and 36.90 (7)° with the least-squares plane through the tetra-hydro-pyridine ring. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond, generating an S(6)(More)
In the title compound, C(21)H(25)NO(3)·C(2)H(4)O(2), the piperidone ring adopts a chair conformation. The two meth-oxy groups are nearly coplanar with the aromatic rings to which they are attached. The dihedral angle between the two aromatic rings is 60.9 (2)°. There are two short intra-molecular N-H⋯O contacts. The crystal packing is stabilized by(More)
In the title compound, C(27)H(32)N(2)O(4), the piperidine and tetra-hydro-pyridine rings adopt chair and half-chair conformations, respectively. The dihedral angle between the two phenyl rings is 32.9 (1)°. The mol-ecular structure is stabilized by a strong intra-molecular O-H⋯O hydrogen bond, generating an S(6) motif. In the crystal, inter-molecular C-H⋯O(More)
