Abstract
A mild and greener protocol was developed for C-C (C(sp3)-H functionalization) and C-N bond formation to synthesize functionalized tacrine derivatives using a biodegradable and reusable deep eutectic solvent [(DES) formed from N,N'-dimethyl urea and L-(+)-tartaric acid in a 3 : 1 ratio at 80 °C]. The condensation of 9-chloro-1,2,3,4-tetrahydroacridines with a variety of aromatic aldehydes gave unsaturated compounds via C(sp3)-H functionalization (at the C-4 position) with good yields. The substituted N-aryl tacrine derivatives were obtained from the condensed products of 9-chloro-1,2,3,4-tetrahydroacridine with substituted anilines via the nucleophilic substitution reaction (SN2 type) in the DES with good yields. This is the first example of C4-functionalized tacrine derivatives, highlighting the dual capacity of the DES to serve as both a catalyst and a solvent for facilitating C-N bond formation on acridine. The generated compounds were evaluated for acetyl/butyrylcholinesterase (AChE/BChE) and α-glucosidase inhibitory activity. It was found that the majority of the compounds reported here were significantly more potent inhibitors than the standard inhibitor tacrine (AChE IC50 = 203.51 nM; BChE IC50 = 204.01 nM). Among the compounds screened, 8m was found to be more potent with IC50 = 125.06 nM and 119.68 nM towards AChE and BChE inhibition respectively. The α-glucosidase inhibitory activity of the compounds was tested using acarbose as a standard drug (IC50 = 23 100 nM) and compound 8j was found to be active with IC50 = 19 400 nM.

Abstract
A method for the synthesis of diverse polysubstituted quinolines from readily available acrylic acids and anthranils has been developed. The weakly coordinating -COOH directing group, which can be tracelessly removed in the cascade cyclization, is essential for this reaction. Diverse polysubstituted quinolines were obtained under mild reaction conditions with simple H2O and CO2 as byproducts. More importantly, 1,2,3,4-tetrahydroacridine, which is the core skeleton of tacrine (an Alzheimer's disease drug), was conveniently synthesized.
