Abstract:
A powerful EnT photocatalyst 4CzMeBN has been developed and utilized in the synthesis of cis-fused azetidines via dearomative [2+2] cycloaddition under visible light. The photocatalyst 4CzMeBN is a donor-acceptor cyanoarene and features high triplet state energy and long lifetime of triplet state, which would be an alternative to widely used EnT photocatalyst Ir[dF(CF3)ppy]2(dtbbpy)PF6. The photochemical [2+2] cycloaddition provides a facile method to synthesize valuable dihydroisoquinolone-fused azetidines with high efficiency. © 2024 Wiley-VCH GmbH.
