An isovaleramide analog having at least one of an increased potency, an increased half-life, and an increased stability compared to isovaleramide. The isovaleramide analog is a cyclic analog or a noncyclic analog. The isovaleramide analog is formulated into a pharmaceutical composition. A method of treating a central nervous system condition or disease is also disclosed. The method comprises administering an isovaleramide analog to a patient suffering from the central nervous system condition or disease.
A novel method for asymmetric synthesis of both enantiomers of α-substituted carboxylic acid derivatives from optically active 1-chlorovinyl p-tolyl sulfoxides and lithium ester enolates with 1,4-chiral induction from the sulfur chiral center

Treatment of optically active 1-chlorovinyl p-tolyl sulfoxides, which were synthesized from symmetricalketones and (R)-(−)-chloromethyl p-tolyl sulfoxide in three steps, with lithium enolate of carboxylic acid tert-butyl esters gave optically active adducts having a substituent at the α-position with high 1,4-chiral induction from the sulfur chiral center in high yields. The adducts were converted

out with an ester enolate generated from excess carboxylic acid tert-butyl ester with LDA in the presence of HMPA, the diastereomer of the adduct was obtained. By using the two reaction conditions for the generation of the ester enolate, a new method for asymmetricsynthesis of both enantiomers of carboxylic acidderivatives having a substituent at the α-position from the one chiral source, (R)-(−)-chloromethyl
