1 Source of material

4–Methylbenzaldehyde (6.5043 g, 0.0541 mol), methyl propiolate (9.1022 g, 0.1082 mol) and acetic acid (catalytic dose) were added to a 500 ml three-necked flask. After the reaction solution was heated to 90 °C, cyclohexylamine (5.3685 g, 0.0541 mol) was added and refluxed for 3 h, then naturally cooled to room temperature. A yellow precipitate was collected and recrystallized from 95 % ethanol, yield 73.5 %. Yellow block crystals were obtained from the filtrate by recrystallization.

2 Experimental details

Using Bruker APEX2 and Bruker SAINT, 1 the structure was solved with the Sheletl (Bruker, 2008) 2 structure solution program and refined with the Shelxl2018/3 (Sheldrick, 2018) 3 , 4 refinement package.

3 Comment

1,4–Dihydropyridine is a very important class of nitrogen-containing heterocyclic compounds, which has been widely used in biology, medicine and organic catalysis. 5 So far, many attempts have been made by researchers to synthesize them, such as ultrasonic method, 6 metal catalysis, 7 nano catalysis, 8 acid catalysis, 9 enzyme catalysis 10 and so on.

The title compound crystallizes in the triclinic space group, P 1 . The conformational details and atom numbering of the title compound are shown in the Figure 1. 1,4–Dihydropyridine ring adopts a flat-boat conformation when the two methoxycarbonyl groups are twisted in opposite directions. The plane of the 4-p-tolylgroup in this compound is approximately perpendicular to the 1,4-dihydropyridine ring. In this crystal the molecules of the title compound form centrosymmetric dimers due to the C12–H12⋯O2 hydrogen bond (H⋯C = 2.718 Å, C–H⋯O = 126.29°). These dimers furthermore generate infinite chains via weak C(17)–H(17)⋯O4 (H⋯O = 2.675 Å, C–H⋯O = 150.39°) and C5–H5⋯O4 (H⋯O = 2.508 Å, C–H⋯O = 156.46°) intermolecular hydrogen bonds. The bond lengths and bond angles of the crystal structure are within a reasonable range. 11 17
