## Abstract The most convenient and direct route to α‐hydroxy‐β‐dicarbonyl compounds is the oxidation of readily accessible 1,3‐dicarbonyls. Hence, this type of oxidation is an intensively investigated field. In this short review, we present and compare α‐hydroxylations using various oxidants such

## Abstract Three α‐cyclopropyl β‐dicarbonyl compounds have been used as probes for α‐radicals as electrophilic reaction intermediates in a cerium‐catalyzed α‐hydroxylation reaction with molecular oxygen. Since the cyclopropyl group did not ring‐open to products with a butenyl moiety, but was retai
