New discoveries in chemical research and development in 2021, Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, and development of new chemical products and materials. 495-40-9, Name is 1-Phenylbutan-1-one, SMILES is CCCC(C1=CC=CC=C1)=O, in an article , author is Li, Meng-Fan, once mentioned of 495-40-9, Recommanded Product: 495-40-9.
The combination of Pd(TFA)(2) and an N,N’-disulfonyl bisimidazoline ligand shows high catalytic activity and excellent asymmetric induction in the addition of arylboronic acids to cyclic N-sulfonyl ketimines including benzo[d]-isothiazole-1,1-dioxides, benzo[e][1,2,3]oxathiazine-2,2-dioxides, and 1,2,5-thiadiazole-1,1-dioxides, by which three types of chiral quaternary carbon-containing sultams with substantial substitution diversity were synthesized with high yields and excellent enantioselectivities (up to >99% ee). The current catalysis demonstrated a remarkable tolerance to oxygen and thus provided an operationally simple approach for constructing enantioenriched cyclic quaternary stereocenters.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield. If you are hungry for even more, make sure to check my other article about 495-40-9, Recommanded Product: 495-40-9.
