2-(3-Chloro-4-hydroxy-phen-yl)-N-(3,4-dimethoxy-pheneth-yl)acetamide

Crystal structure of mandipropamid

In the title compound, C23H22ClNO4 (systematic name: (RS)-2-(4-chloro-phen-yl)-N-{2-[3-meth-oxy-4-(prop-2-yn-1-yl-oxy)phen-yl]eth-yl}-2-(prop-2-yn-yloxy)acetamide), an amide fungicide, the dihedral angle between the chloro-benzene and benzene rings is 65.36 (6)°. In the crystal, N-H⋯O hydrogen bonds lead to zigzag supra-molecular chains along the c axis (glide symmetry). These are connected into layers by C-H⋯O and C-H⋯π inter-actions; the layers stack along the a axis with no specific inter-molecular inter-actions between them.

N-Benzyl-2-(3-chloro-4-hy-droxy-phen-yl)acetamide

The title compound, C(15)H(14)ClNO(2), was synthesized as part of a project to generate a combinatorial library based on the fungal natural product 2-(3-chloro-4-hy-droxy-phen-yl)acetamide. It crystallizes as non-planar discrete mol-ecules [the peripheral 3-chloro-4-hy-droxy-phenyl and benzyl groups are twisted out of the plane of the central acetamide group, with N-C-C-C and C-C-C-C torsion angles of -58.8 (3) and 65.0 (2)°, respectively] linked by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.
