In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 35857-89-7, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 35857-89-7, name is 6-Chloropyridazine-3-carbonitrile. In an article£¬Which mentioned a new discovery about 35857-89-7
Zinc-Catalyzed Hydroxyl-Directed Regioselective Ring Opening of Aziridines in SN2 Reaction Pathway
In this protocol, a zinc-catalyzed catalytic regioselective ring opening of electronically and sterically unbiased 2,3-aziridinyl alcohols has been accomplished. The directing effect of the hydroxyl moiety enables the selective nucleophilic attack to the C-3 position of 2,3-aziridinyl alcohols with various aromatic amines and thiophenols as nucleophiles. This operationally simple reaction provides convenient access to a variety of amino alcohols and hydroxyl sulfides in excellent regiocontrol. Moreover, simple derivatization of the ring opening product establishes a general strategy to approach internal vicinal diamines in regioselective and diastereomerically pure form.
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 35857-89-7, help many people in the next few years.Recommanded Product: 35857-89-7
