S)-y-Butyrolactone-y-carboxylic acid (III, R = H) (levorotatory in water, dextrorotatory in methanol), in form of its methyl ester III (R = CH 3 ), was reduced to (S)-( -)-1,2,5-pentanetriol (IV) the absolute configuration of which was determined by correlation with (R)-( + )-glycerraldehyde. The probable absolute configuration of (R)-y-valerolactone-y-carboxylic acid (VII, R = H) (dextrorotatory in ' water; levorotatory in methanol) has been derived by comparing ORD curves of the both acids studied, and their derivatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
