As widely used building blocks, allyl alcohols can directly participate in the synthesis reaction without pre-functionalization. In recent years, the migration reaction of allyl alcohols has received great attention, and such reactions are often realized by semipinacol or neophyl rearrangement, providing a powerful strategy for the synthesis of various important carbonyl compounds. The latest progress of radical-initiated group migration reactions involving diaryl allyl alcohols as synthons systematically is reviewed, the scope, limitations and some mechanisms of the reaction are discussed, and the challenges and future development trends in this field are prospected.
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.
