Abstract

The Front Cover highlights investigations of the reactivity of Cannabigerol (CBG) in organic solvents under both photochemical and acid catalyzed conditions, pointing out the key role of the photoexcited CBG* in the selective formation of a 2,2-disubstituted-chromane derivative (green path). On the other hand, in the presence of Brønsted-Lowry acids, two tertiary carbocations are competitively generated (I+, II+, orange and blue paths). Finally, when performing the reaction in toluene in the presence of BF3*OEt2, a Friedel Crafts-like alkylation of the solvent was noticed (purple paths). More information can be found in the Research Article by Daniele Merli, Stefano Protti, and co-workers (DOI: 10.1002/cptc.202400157).

封面:光化学与热酸催化的大麻萜醇(CBG)环化:意想不到的选择性(ChemPhotoChem 11/2024)
封面重点介绍了在光化学和酸催化条件下,大麻萜醇(CBG)在有机溶剂中的反应性研究,指出了光激发的 CBG* 在选择性生成 2,2-二取代-铬烷衍生物(绿色路径)中的关键作用。另一方面,在布氏-洛氏酸存在的条件下,两个叔碳基竞争性地生成(I+、II+,橙色和蓝色路径)。最后,在有 BF3*OEt2 存在的甲苯中进行反应时,发现溶剂发生了类似 Friedel Crafts 的烷基化反应(紫色路径)。更多信息,请参阅 Daniele Merli、Stefano Protti 及合作者的研究文章(DOI: 10.1002/cptc.202400157)。
