Treatment of 1,4,4-trimethyl-3,4-dihydroquinolin-2(1H)-one (2) with lithium diisopropylamide (LDA) followed by a wide range of electrophiles give the corresponding 4,4-dimethyl-3-substituted-3,4-dihydroquinolin-2-ones (3-13), providing a very mild electrophilic substitution of the 4,4-dimethyl-1,2,3,4-tetrahydroquinoline core.

pH-responsive drug carriers derived from polymers containing weak base groups have been shown to improve the antitumor effect of chemotherapeutics. The common interpretation is that a "proton sponge effect" caused by pH-responsive polymers facilitates endosomal membrane destruction and accelerates cytoplasmic...

Density functional theory computations [MP2/6-31G(d)//B3LYP/6-31G(d)] on the deaggregation of lithium diisopropylamide (LDA) dimer solvated by two tetrahydrofuran ligands to give the corresponding trisolvated monomer show eight structurally distinct minima. The barriers to exchange are comparable to those expected from experimental...

Ortholithiations of a range of arenes mediated by lithium diisopropylamide (LDA) in THF at -78 degrees C reveal substantial accelerations by as little as 0.5 mol % of LiCl (relative to LDA). Substrate dependencies suggest a specific range of reactivity...
