The title compound, C(18)H(22)N(2)O(7), was synthesized by the 1,3-dipolar cyclo-addition reaction of but-3-en-2-one, diethyl 2-amino-malonate and 2-nitro-benzaldehyde. In the mol-ecule, the pyrrolidine ring possesses an envelope conformation. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds are present in the crystal structure.

g -Aminobutiric acid (GABA), the major inhibitory neurotransmitter in the central nervous system has two major receptor subtypes (GABAA and GABAB). GABAB receptors are activated by the antispastic and muscle relaxant agent, Baclofen, which is a lipophilic derivative of GABA. Since 1962 several strategies have been reported for the synthesis of baclofen.In this study an approach has been made to...

Abstract The condensation of tacrine aminopolymethylene derivatives with diethyl (ethoxymethylidene)malonate led to the new hybrid compounds—conjugates, which were effective inhibitors acetylcholinesterase (AChE) (IC 50 up 0.538 μM) and butyrylcholinesterase 0.0314 μM). They can displace propidium iodide from peripherical anionic site AChE at level reference drug donepezil demonstrate a weak an...

Glucosamine has been selected as a cheap and readily available chiral scaffold for the synthesis of a series of novel enantiomerically pure bifunctional organocatalysts bearing a tertiary amino group in proximity to a (thio)urea group. The catalytic behaviour of these compounds, both as neutral and N-protonated species, was investigated using the addition of acetylacetone to β-nitrostyrene as a...
