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. 17924-92-4, Name is (S,E)-14,16-Dihydroxy-3-methyl-3,4,5,6,9,10-hexahydro-1H-benzo[c][1]oxacyclotetradecine-1,7(8H)-dione, molecular formula is , belongs to pyrrolines compound. In a document, author is Hirai, Sho, Formula: C18H22O5.
Acid promoted dimerization of beta-amino-alpha,beta-unsaturated amides affording bis(functionalized) pyrrolinones
Polysubstituted pyrrolinones were synthesized by the dimerization of 3-amino-2-butenamides via treatment with 0.5 equiv p-TsOH under mild reaction conditions, including oxidation and 1,2-migration of the methyl group. This method is practically advantageous compared to the conventional methods for the preparation of pyrrolinones, because it does not require difficult experimental manipulations and special reagents such as metal catalysts and oxidants. Because the structures of beta-amino-alpha,beta-unsaturated amides can be easily modified by changing the precursors, beta-keto amide and amine, synthesis of diverse pyrrolinones is possible.

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 17924-92-4, in my other articles. Formula: C18H22O5.
