Abstract:Z and E isomers of 3-methyl-3-(carboxymethyl)hexahydro-1 (3H)-isobenzofuranones (I), lactones of 3-hydroxy-3-(2-carboxycyclohexyl) butyric acids (II), were prepared and tested on cholesterol biosynthesis in vitro. Compound I of the Z series was prepared through its ethyl ester by hydrogenation, over Rh/Al2O3 catalyst, of the phenyl ring of 3-methyl-3-[(ethoxycarbonyl)methyl]-1(3H)-isobenzofuranone. Compound I of the E series was prepared, through its ethyl ester, by Reformatsky reaction from ethyl (E)-2-acetyl… Show more
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.
