A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 168960-19-8, Name is ((1S,4R)-4-Aminocyclopent-2-en-1-yl)methanol hydrochloride, molecular formula is C6H12ClNO. In an article, author is Dai, Zonghao,once mentioned of 168960-19-8, Recommanded Product: 168960-19-8.
A phosphine-catalyzed tandem cyclization reaction has been developed to provide a series of chromeno[4,3-b]pyrrole derivatives, which contain three consecutive asymmetric centers. The reaction has a good yield, excellent stereoselectivity, and Z/E selectivity. The new method is simple, requires only mild conditions, and shows tolerance for various functional groups. Similarly, this reaction can be catalyzed by a chiral phosphine catalyst to achieve asymmetric synthesis.
