In the presence of chiral organic catalysts, the optically active 4H-chromine was synthesized from the multicomponent condensation of 5,5-dimethylcyclohexane-1,3-dione with malononitrile and methylene-active compound, and the specific angle of rotation of the compounds was determined in the AUTOPOL-III polarimeter and their structures were confirmed by the X-ray spectroscopic analysis method. These optically active 2-amino-4-aryl-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-4H-chromen-3-carbonitriles were effective inhibitors of α-glycosidase, the cytosolic carbonic anhydrase I and II isoforms (hCA I and II), and acetylcholinesterase (AChE) enzymes with Ki values in the range of 21.33 ± 1.11 to 40.24 ± 10.78 μM for hCA I, 28.91 ± 6.51 to 59.97 ± 15.62 μM for hCA II, 18.16 ± 3.18 to 66.57 ± 1.36 μM for α-glycosidase, and 8.68 ± 0.93 to 102.61 ± 24.96 μM for AChE.
