摘要

建立了光诱导的n -丙烯醛腙/不饱和香豆素与硫氰酸酯的两个自由基硫氰化环化体系，该体系高效地合成了多种硫氰化吡唑酮/多环香豆素，并具有良好的选择性。同时，各种控制实验（放大操作、取代基转化、自由基捕获/开-关操作）探索了硫氰化体系的优点和合理的环化过程。

Photo-induced tandem cyclization of unsaturated amides with thiocyanates to access thiocyanated heterocycles

Photo-induced two-radical thiocyanation cyclization systems of N-acryloyl aldehyde hydrazones/unsaturated coumarins with thiocyanate were completed, efficiently producing diverse thiocyanated pyrazolones/polycyclic coumarins with good selectivity. Meanwhile, various control experiments (scaled-up operations, substituent transformations, and radical capture/light-on–off operations) explored the merits and the plausible cyclization process of the thiocyanation systems.
