Diethyl 4-(2,4-dichloro-phen-yl)-2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate
Abstract:
In the title compound, C(19)H(21)Cl(2)NO(4), the dihydro-pyridine ring adopts a flattened boat conformation. The dichloro-phenyl ring is oriented almost perpendicular to the planar part of the dihydro-pyridine ring [dihedral angle = 89.1 (1)°]. An intra-molecular C-H⋯O hydrogen bond is observed. In the crystal structure, mol-ecules are linked into chains along the b axis by N-H⋯O hydrogen bonds.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
