被撤回的出版物: Photocatalyzed Dehydroxylative Amination of Phenols: A Ring-Expansion Approach for Medium-Sized Benzolactams (Retracted article. See vol. 25, pg. 5400, 2023)

An efficient photopromoted dehydroxylative ring-expansion approachto eight-membered benzolactams that employ phthalocyanine iron(II)as the photosensitizer has been developed. This cascade reaction protocol,featuring a visible-light-promoted dehydroxylative amination and oxidativering-expansion lactamization of 4-hydroxyphenols with N-alkyl-4-piperidinones, provides a green and reliable approach toa diverse array of valuable eight-membered benzolactams with highchemo- and regioselectivity.

Automated summary

An efficient photopromoted dehydroxylative ring-expansion approach has been developed using phthalocyanine iron(II) as the photosensitizer to synthesize a variety of valuable eight-membered benzolactams with high chemo- and regioselectivity.
