“…Camphorsulfonic acid 30 was obtained from camphor, according to the procedure [30]. By its refluxing in toluene with iodine in the presence of triphenylphosphine, camphor iodine derivative 31 was synthesized [31]. To study the influence of nature of the linker on the result of the catalyst reaction, sulfonyl chloride 32 and ketopinic acid 33 [32] that was transformed into corresponding acid chloride 34 were obtained.…”

A number of new chiral bispidines containing monoterpenoid fragments have been obtained. The bispidines were studied as ligands for Ni-catalyzed addition of diethylzinc to chalcones. The conditions for chromatographic analysis by HPLC-UV were developed, in which the peaks of the enantiomers of all synthesized chiral products were separated, which made it possible to determine the enantiomeric excess of the resulting mixture. It was demonstrated that bispidine-monoterpenoid conjugates can be used as the ligands for diethylzinc addition to chalcone C=C double bond but not as inducers of chirality. Besides products of ethylation, formation of products of formal hydrogenation of the chalcone C=C double bond was observed in all cases. Note, that this formation of hydrogenation products in significant amounts in the presence of such catalytic systems was found for the first time. A tentative scheme explaining the formation of all products was proposed.

“…DFT computational codes are used in practice to investigate the structural, magnetic and electronic properties of molecules, materials and defects. In DFT, the functional is the electron density which is a function of space and time [13,14]. The electron density is used in DFT as the fundamental property.…”

An efficient and straightforward methodology for the esterification of various N‐heteroarene methanols using benzoyl cyanides as acylating sources through a simply mixing conditions has been reported. The acyl groups were in‐situ generated via chemoselective C–CN bond cleavage to give the N‐heteroarenemethyl esters. This process features in readily accessible starting materials and offers an easy operational procedure, and broad substrate scope with excellent selectivity.
