(R)-2-Phenoxypropanoate ester was efficient chiral resolving agent in acylative KR of racemic cyclic alkylamines; highest selectivity was observed for 2-methylpiperidine with predominant formation of (R,R)-amide, which was confirmed by DFT modelling.

Nowadays, it is still important to develop effective anti-opisthorchiasis agents. In this work, we tested a complex of praziquantel (PZQ) with a plant origin compound—disodium glycyrrhizinate—in the ratio 1:10 PZQ:Na2GA, containing 11-fold less o
