A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Quality Control of: tert-Butyl 4-ethynylpiperidine-1-carboxylate, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 287192-97-6, Name is tert-Butyl 4-ethynylpiperidine-1-carboxylate, molecular formula is C12H19NO2. In a Article, authors is Alexander, Juliana R.，once mentioned of 287192-97-6
An enantioselective copper-catalyzed azide-alkyne cycloaddition (E-CuAAC) is reported by kinetic resolution. Chiral triazoles were isolated in high yield with limiting alkyne (up to 97:3 enantiomeric ratio (er)). A range of substrates were tolerated (>30 examples), and the reaction was scaled to >1 g. The er of a triazole product could be enhanced by recrystallization and the recovered scalemic azide could be racemized and recycled. Recycling the azide allows efficient use of the undesired azide enantiomer.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 287192-97-6, help many people in the next few years.Quality Control of: tert-Butyl 4-ethynylpiperidine-1-carboxylate
