In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 20733-11-3, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 20733-11-3, name is 4-Methoxypyridazine. In an article£¬Which mentioned a new discovery about 20733-11-3
A short and efficient synthesis of 3,4-dialkoxypyrroles
3,4-Dialkoxypyrroles are obtained in four steps from commercially available 2,5-dimethoxy-2,5-dihydrofuran (1). The dihydrofuran 1 is first oxidized by KMnO4 to the diol 2 which is bis-alkylated to 3a-d. Reaction of the in situ generated dialdehydes with a primary amine affords the N- substituted dialkoxypyrroles 4a-m. N-Benzyl-3,4-dialkoxypyrroles and N- allyl-dialkoxypyrroles are cleaved by sodium in liquid ammonia affording N- unsubstituted dialkoxypyrroles 5a-c in good overall yield.
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 20733-11-3, help many people in the next few years.Recommanded Product: 20733-11-3
