On June 30, 2021, Kang, Juyeon; Ham, Seunghwan; Seong, Chaehyeon; Oh, Chang Ho published an article.Application In Synthesis of 1,2-Dimethoxybenzene The title of the article was Synthesis of [6,6,m]-Tricyclic Compounds via [4+2] Cycloaddition with Au or Cu Catalyst. And the article contained the following:
The [6,6,6]- and [6,6,7]-tricyclic compounds I [R = H, trimethylsilyl, methoxycarbonyl; R1 = H, Me; R2 = H, OMe, propan-2-yl; R3 = H, OMe; R4 = H, OMe; R5 = H, OH, Me, (tert-butyldimethylsilyl)oxidanyl; R6 = H, Me; R7 = H, Me, methoxycarbonyl, (tert-butyldimethylsilyl)oxidanyl; R8 = H, Me, methoxycarbonyl; R9 = H, OH] and II via intramol. [4+2] cycloaddition by gold or copper catalysts have been synthesized. Substrates for cyclization were prepared by coupling reactions between eight types of diynes e.g., di-Me 2,2-di(prop-2-yn-1-yl)malonate and four types of aromatic moieties 2-Br-3-R4-4-R3-5-R2-C6HC(O)R1. Eleven tricyclic compounds I and II have been successfully synthesized. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Application In Synthesis of 1,2-Dimethoxybenzene
