Carbocycles from donor–acceptor cyclopropanes
TLDR
This review summarizes research directed towards the formation of carbocyclic adducts from donor-acceptor cyclopropanes and focuses on annulation and cycloaddition reactions mediated by Lewis or protic acid, bases, or thermal conditions.Abstract:
This review summarizes research directed towards the formation of carbocyclic adducts from donor–acceptor cyclopropanes. The focus of the review is on annulation and cycloaddition reactions (both inter- and intramolecularly) mediated by Lewis or protic acid, bases, or thermal conditions. Rearrangements resulting in carbocycles and those reactions mediated by transition metal catalysis have been excluded.read more
