Ortho-substitutedarylketones are prepared from N-[2-(dimethylamino)ethyl]-N-methylbenzamides via ortho lithiation of intermediate α-amino alkoxides, formed in situ by addition of RLi. An ortho lithiation of N-[2-(dimethylamino)ethyl]-N-methylbenzamide is also described.

a search for medications for cocaine abuse. Herein we describe the synthesis and biologicalevaluation of an array of 2-aminopentanophenones. This array has yielded selective inhibitors of the dopamine and norepinephrinetransporters with little effect upon serotonin trafficking. A subset of compounds had no significant affinity at 5HT1A, 5HT1B, 5HT1C, D1, D2, or D3 receptors. The lead compound, racemic

Binding to the neuronal voltage-dependent sodiumchannel (NVSC) was evaluated for 12 5-phenylhydantoins which systematically varied either log P and/or 5-phenyl ring orientation. The linear correlation of log P with in vitro sodiumchannelbindingactivity (log IC50) for hydantoins 1-12 and diphenylhydantoin (DPH) (r2 = 0.638) suggested that simple partitioning into the lipid phase is important but

We report here a simple procedure for the preparation of 4,6-disubstituted- and 3,4,6-trisubstituted-2-pyridones and 3-substituted-isoquinol-1-ones, in good yields, from lithium dienediolates and nitriles.
We report that the nucleophilic acyl substitution reaction of aliphatic and (hetero)aromaticamides by organolithium reagents proceeds quickly (20 s reaction time), efficiently, and chemoselectively with a broad substrate scope in the environmentally responsible cyclopentyl methyl ether, at ambient temperature and under air, to provide ketones in up to 93 % yield with an effective suppression of the
