Synthesis of new photochromic diarylethenes of cyclopentenone series by Nazarov reaction

An effective method is proposed for the synthesis of photochromic diarylethenes of cyclopentenone series with SnCl 4 -catalyzed 4π-electron cyclization of divinyl ketones by Nazarov reaction as the key step. It was shown that the introduction of an aryl group at position 4 of the cyclopentenone ring...

Description
Summary:An effective method is proposed for the synthesis of photochromic diarylethenes of cyclopentenone series with SnCl 4 -catalyzed 4π-electron cyclization of divinyl ketones by Nazarov reaction as the key step. It was shown that the introduction of an aryl group at position 4 of the cyclopentenone ring significantly improved the quantum yield of diarylethene photocyclization reaction.
