A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Application In Synthesis of 3-Furanmethanol, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4412-91-3, Name is 3-Furanmethanol, molecular formula is C5H6O2. In an article, author is Liu, Yang-Zi,once mentioned of 4412-91-3.
Palladium-Catalyzed Asymmetric [4+3] Cyclization of Trimethylenemethane: Regio-, Diastereo-, and Enantioselective Construction of Benzofuro[3,2-b]azepine Skeletons
The palladium-catalyzed asymmetric [4+3] cyclization of trimethylenemethane donors with benzofuran-derived azadienes furnishes chiral benzofuro[3,2-b]azepine frameworks in high yields (up to 98 %) with exclusive regioselectivities and excellent stereoselectivities (up to >20:1 d.r., >99 % ee). This catalytic asymmetric [4+3] cyclization of Pd-trimethylenemethane can enrich the arsenal of Pd-TMM reactions in organic synthesis. In addition, this strategy provides an alternative approach to chiral azepines by a transition-metal-catalyzed asymmetric [4+3] cyclization.
