particularly efficient organophotocatalyst to promote lactone formation under visible-light irradiation within 6 h. Ultimately, it was found that this protocol could enable the formation of racemic herbaric acid.
在此,我们研究了一种新的有机光催化方案,能够制备 3-取代苯酞。从这项工作中,1,2,3,5-四(咔唑-9-基)-4,6-二氰基苯 (4CzIPN) 被证明是一种特别有效的有机光催化剂,可在 6 小时内在可见光照射下促进内酯形成. 最终,发现该方案可以形成外消旋草本酸。
