Research speed reading in 2021. The prevalence of solvent effects catalysis has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 154445-78-0, Name is 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride, belongs to thiazines compound, is a common compound. In a pantent, author is Gao, Yong, once mentioned the new application about 154445-78-0, Application In Synthesis of 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride.
Tunable Synthesis of Disulfide-Functionalized Enaminones and 1,4-Thiazines via the Reactions of Enaminones and ss-Aminoethanethiol
The reactions of ss-aminoethanethiol with N, N-dimethyl enaminones are performed to selectively provide disulfide-functionalized enaminones and 1,4-thiazines. By performing the reaction in water and catalyst-free conditions, the transamination and oxidative S-S coupling between the two substrates take place to give disulfide-functionalized enaminones. On the other hand, by using identical starting materials, the employment of the CuI catalyst in dimethyl sulfoxide enables the selective generation of 1,4-thiazines via tandem transamination and C(sp(2))-H bond thiolation.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 154445-78-0, you can contact me at any time and look forward to more communication. Application In Synthesis of 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride.
