Next, we opted to test the activity and selectivity of Ru3 under classical conditions (in a solution), similar to those used frequently in stereoretentive catalysis. In this context, the CM reaction of allylbenzene and (Z)-1,4-diacetoxy-2-butene ( ) is commonly considered the model reaction. Although THF is the most frequently used solvent with benchmark Ru2, we decided to perform a small solvent screening study to check if the same solvent is also optimal for Ru3. To do so, stereoselective catalyst Ru2. Finally, in the case of complex polyfunctional molecule of Baricitinib analogue (33) quinoxaline-derived Ru2 seems to slightly outdistance Ru2 in terms of yield and selectivity (Scheme 4C).
