(S)-2-(Methoxymethyl)pyrrolidine, cas is 63126-47-6, it is a common heterocyclic compound, the chiral-catalyst compound, its synthesis route is as follows.,63126-47-6

General procedure: A mixture of aldehyde (1.97 mmol), amine (1.97 mmol), acetylene (2.95 mmol), and thecorresponding supported Au catalyst (1percent wt, 60 mg, 0.002 mmol) was heated at 60 ¡ãC for 8 h,after which time the solution was cooled and the catalyst was removed by filtration. The filtrate wasevaporated under reduced pressure to afford propargylamine 5. Yields were determined by integration of the 1H-NMR spectra of the crude reaction mixtures. After separation and washing with n-pentane,the catalyst was reused intact for the next reaction without any further pre-treatment.

As the rapid development of chemical substances, we look forward to future research findings about 63126-47-6
