Just accepted! New article about making more efficient enatioselective organocatalytic reactions

Juanvi has worked hard in this project and now the first results have just come out. The central idea is to generate in situ, the carbonyl compound, via oxidation of an alcohol, which is involved in a subsequent asymmetric organocatalytic … Continue reading

Enhancing the activity of a squaramide as organocatalyst through the novel concept of trifunctionality

It is well known the lower activity of organocatalysts as compared to most metal catalysts. As a result, developing new and more potent organocatalysts focuses a great deal of interest both for science and chemical industry. Herein, we present our … Continue reading
