Reaction of 5-hydroxypyrazolidines (I) with acetophenone on the surface of basic adsorbents affords along with the expected 5-benzoylmethyl derivative (III) its regioisomer (IV), which is formed via retro-Michael degradation of the starting compounds followed by an attack of crotonaldehyde at the imide nitrogen atom. -(SVIRIDOVA*, L.

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.
