Journal of the Chemical Society C: Organic Pub Date: DOI: 10.1039/J39700001334

Abstract

Evidence is presented which firmly establishes the R-configuration at C-2 in monocrotalic acid. In addition, (–)-methyl 2-hydroxy-2-methyl-3-oxobutanoate (methyl acetolactate) is shown to have the R-configuration.
