Kong, Wangqing published the artcileExclusive 1,2-Aryl Shift in Platinum(II) Chloride-Catalyzed Cyclization of 1-(Indol-2-yl)-2,3-allenols, Category: tetrahydropyran, the publication is Advanced Synthesis & Catalysis (2012), 354(11-12), 2339-2347, S2339/1-S2339/79, database is CAplus.
An efficient cyclization of 1-(indole-2-yl)-2,3-allenols in the presence of platinum(II) chloride leading to polysubstituted carbazoles via 1,2-Me or an exclusive 1,2-aryl migration of the metal-carbene intermediate was observed The reaction proceeds via the intermediacy of a metal carbene intermediate, which induces the carbon-carbon bond cleavage via 1,2-migration to afford the products.
Advanced Synthesis & Catalysis published new progress about 27943-46-0. 27943-46-0 belongs to tetrahydropyran, auxiliary class Tetrahydropyran,Alkynyl,Ether, name is 2-((2-Methylbut-3-yn-2-yl)oxy)tetrahydro-2H-pyran, and the molecular formula is C10H16O2, Category: tetrahydropyran.
