“…The most downfield signals in the range 81.16 -89.31 ppm belong to carbon triple bond. Moreover, a carbon atom of the triple bond associated with the cycle resonates in a weaker field, because of the proximity of the hydroxyl group at C 1 (4) . In propargyl derivatives there is strong shielding effect (~ 10 ppm) due to the methylene carbon adjacent to the OH group having a triple bond.…”

“…A prospective solution to the hunger problem may be offered through compounds that have the ability to increase crop yield, for example by making crops more drought resistant. It is well known that the use of piperidine-containing diacetylene glycols may increase the growth of plants multifold [1][2][3][4][5]. In addition, plants which were processed by piperidine-containing diacetylene glycols prove to be more resistant to drought, temperature changes and diseases [1][2][3][4][5].…”

Synthesis routes of novel piperidine-containing acetylenes are presented. The new molecules are expected to exhibit plant growth stimulation properties. In particular, the yield in a situation of drought is expected to increase. Our synthesis makes use of the Favorskii reaction between cyclohexanone/piperidone and triple-bond containing alcohols. The structures of the obtained molecules were determined using nuclear magnetic resonance (NMR). The electronic structure and geometries of the molecules were studied theoretically using first-principles calculations based on density functional theory. The calculated geometries agree very well with the experimentally determined ones, and also allow us to determine bond lengths, angles and charge distributions inside the molecules.
