Chemistry is an experimental science, COA of Formula: C14H15NO, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 23364-44-5, Name is (1S,2R)-2-Amino-1,2-diphenylethanol
Copper Bis(oxazoline)-Catalyzed Enantioselective Alkynylation of Benzopyrylium Ions
The stereocontrolled construction of biologically relevant chromanones and tetrahydroxanthones has been achieved through the addition of alkynes to benzopyrylium trilfates under the influence of copper bis(oxazoline) catalysis. Excellent levels of enantiocontrol (63?98 % ee) are achieved in the addition of a variety of alkynes to an array of chromenones with a hydrogen in the 2-position. Promising levels of enantiocontrol (54?67 % ee) are achieved in the alkynylation of chromenones with esters in the 2-position, generating tertiary ether stereocenters resembling those frequently found in naturally occurring metabolites.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C14H15NO, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 23364-44-5, in my other articles.
