A Rapid Catalytic Asymmetric Synthesis of 1,3,4-Trisubstituted Pyrrolidines. -Pyrroline derivatives of type (I), readily prepared via 1,3-dipolar cycloaddition of propiolate esters (II), undergo an asymmetric Rh-catalyzed addition of aryl boronic acids to give the title compounds with good to excellent enantioselectivity. -(BELYK*, K.

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.
