Nazarov cyclization: Mechanism, Modern variants & Classical Nazarov cyclizations

The Nazarov cyclization, also known as the Nazarov reaction, is a chemical reaction used in organic chemistry for the synthesis of cyclopentenones. The reaction is typically divided into classical and modern variants, depending on the reagents and substrates employed. It was originally discovered by Ivan Nikolaevich Nazarov (1906–1957) in 1941 while…
