In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Application In Synthesis of (2S,3S)-Butane-2,3-diol, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 19132-06-0, name is (2S,3S)-Butane-2,3-diol. In an article£¬Which mentioned a new discovery about 19132-06-0
Stereospecific conversion of chiral 1,2-cyclic sulfates to chiral imidazolines
The one pot preparation of imidazolines from 1,2-cyclic sulfates is reported. Amidines react with cyclic sulfates to give zwitterionic intermediates, and subsequent intramolecular cyclization affords imidazolines. The preparation of enantiopure stilbene diamine (stien) is achieved by the hydrolysis of its corresponding chiral imidazoline.
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 19132-06-0, help many people in the next few years.Application In Synthesis of (2S,3S)-Butane-2,3-diol
