Hydrogenolysis is an important synthetic method in organic chemistry, and has been widely applied in industrial processes, natural product synthesis, and the removal of waste materials. In practice, most hydrogenolysis reactions have been used for the synthesis of racemic or achiral compounds. Very few studies on asymmetric homogeneous hydrogenolysis have been reported. The first example, repor...
We present a complete and independent list of the dimension-nine operator basis in Standard Model effective field theory by an automatic algorithm based on amplitude-operator correspondence. A ($Y$-basis) is first constructed enumerating Young tableau auxiliary $SU(N)$ group gauge groups, with equation-of-motion integration-by-part redundancies all removed. In presence repeated fields, another ...
This short review focuses on enantiopure planar chiral [2.2]paracyclophanes (pCps), a fascinating class of molecules that possess an unusual three-dimensional core and intriguing physicochemical properties. In the first part review, different synthetic strategies for preparing optically active pCps are described. Although classical resolution methods based synthesis separation diastereoisomeric...
