Indole containing compounds have acquired conspicuous significance due to their wide spectrum of biological activities. Synthesis of a series of enantiomerically pure indole derivatives 3a-r via Friedel–Crafts alkylation of indole 1 with enones 2a-r were described here. The products were isolated in a moderate to excellent yields (upto 89%) with excellent enantioselectivities (upto 99.9% ee). These compounds 3a-r were evaluated for their in vitro α-glucosidase inhibitory activity and some of them were identified as potent inhibitors (IC50 = 4.3 ± 0.13–43.9 ± 0.51 μM) with several fold higher activity than the clinically used α-glucosidase inhibitor, acarbose (IC50 = 840 ± 1.73 μM). To the best of knowledge, this is the first report of the propanone substituted indole ring containing compounds by in vitro α-glucosidase enzyme inhibition.

Paragraph 0026; 0033; 0037, (2017/04/18)
Novel α-Glucosidase inhibitors include propanone substituted indole ring-containing heterocyclic compounds, which are represented by Formula I: Wherein R1 is thiophene, 2,4-di chloro phenyl, 2,6-di chloro phenyl, bromo phenyl, benzyl or nitrophenyl; and R2 is an aryl group, or stereoisomers or pharmaceutically acceptable salts thereof.

A series of novel chiral ligands L1-L4 with an imidazoline-oxazoline framework have been developed as new type of non-symmetric N,N-bidentate ligands. All the chiral ligands were prepared from 2,2-diethylmalonic acid and enantiomerically pure (S)-2-amino-
