(S)-(+)- and (R)-(-)-5-Allyl-5-(1-methyl-2-pentynyl)-2-thiobarbituric acid (1, thiohexital) were prepared. The anesthetic activity (loss of righting reflex) and acute toxicity of the optically pure enantiomers of 1 were compared to the racemic isomer in mice. The S(+) isomer was found to be more potent as an anesthetic agent than the R(-) or RS(+/-) isomers. The therapeutic index was 2.5, 2.4, and 3.2
