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. 90965-06-3, Name is Dimethyl (1-diazo-2-oxopropyl)phosphonate, molecular formula is , belongs to chiral-nitrogen-ligands compound. In a document, author is Chen, Xi, Product Details of 90965-06-3.
Silver-catalyzed intramolecular [4+2] cycloaddition reaction of amide-1, 6-enynes
An efficient intramolecular [4 + 2] cycloaddition reaction of amide-1,6-enynes has been developed, under silver catalysis starting from electron-rich triple bonds. Asymmetric reaction conditions in the presence of Ag salts and chiral atropisomeric MeO-Biphep diphosphine ligands were also investigated and afforded the cyclic amides in good yields and enantiomeric excesses up to 50%.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 90965-06-3, in my other articles.
