Abstract

In the title compound, C(19)H(23)NO(6), the 1,4-dihydro-pyridine ring is twisted slightly from planarity, with a maximum deviation of 0.101 (1) Å, and adopts a very flattened boat conformation. The dihedral angle formed between the plane through the four C atoms of the 1,4-dihydro-pyridine ring and the benzene ring is 84.67 (7)°. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

摘要

在标题化合物C(19)H(23)NO(6)中，1,4-二氢吡啶环略微偏离平面，最大偏差为0.101 (1) Å，并呈现出非常扁平的船式构象。通过1,4-二氢吡啶环的四个C原子的平面与苯环之间形成的二面角为84.67 (7)°。在晶体结构中，分子间的N-H⋯O和C-H⋯O氢键将分子连接成三维网络。
