148461-16-9, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.148461-16-9, Name is (S)-4-(tert-Butyl)-2-(2-(diphenylphosphino)phenyl)-4,5-dihydrooxazole, molecular formula is C25H26NOP, introducing its new discovery.
Enantioselective palladium-catalyzed decarboxylative allylation of carbazolones: Total synthesis of (-)-aspidospermidine and (+)-kopsihainanineA
Functionalized chiral carbazolones with alpha-quaternary carbon centers are formed through the ligand-controlled Pd-catalyzed enantioselective decarboxylative allylic alkylation of carbazolones (see scheme). This catalytic asymmetric reaction was employed as the key step in the total synthesis of aspidospermidine and (+)-kopsihainanineA. Copyright
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 148461-16-9, help many people in the next few years.148461-16-9
