SDS of cas: 123-11-5. Recently I am researching about BOND-CLEAVAGE; CYCLOADDITION; CONSTRUCTION, Saw an article supported by the NSFCNational Natural Science Foundation of China (NSFC) [21871112, 21971090]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Qin, XY; Meng, FT; Wang, MA; Tu, SJ; Hao, WJ; Wang, JY; Jiang, B. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde
Transition metal-catalyzed skeletal rearrangement reactions have rapid advances in organic community. Their development benefits synthetic methodologies by providing versatile and flexible approaches toward special molecular scaffolds with high selectivity. Herein, a gold-catalyzed skeletal rearrangement of alkenes with alkynyl bromides is reported, enabling direct and regioselective generation of more than 50 examples of skeletally diverse tricyclic heterocycles, namely, syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines, with generally good yields. This protocol could tolerate terminal unactivated and internal activated alkenes under air conditions, which is hitherto unreported in gold catalysis and scarcely realized by other metal-catalyzed reactions, thus opening avenues for the regioselective assembly of heterocyclic systems with high efficiency. Aside from examining the scope of this skeletal rearrangement, mechanistic investigations to explain the regioselectivity of forming syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines were conducted by systematic theoretical calculations.
