I found the field of Chemistry very interesting. Saw the article Diastereoselective and Reversed Regioselective Annulations of N-Alkyl Anilines to Julolidines and Lilolidines published in 2020. SDS of cas: 50-84-0, Reprint Addresses Jana, CK (corresponding author), Indian Inst Technol Guwahati, Dept Chem, Gauhati 780139, Assam, India.. The CAS is 50-84-0. Through research, I have a further understanding and discovery of 2,4-Dichlorobenzoic acid
A three-component annulation reaction of N-alkyl anilines, cyclic 1,3-dicarbonyl compounds, and aryl aldehydes to julolidines and lilolidines is reported. The 6 pi-electrocyclization enabled the annulation to proceed with reversed regioselectivity as compared with the annulation that occurs in the Povarov reaction. Both cyclic and acyclic N-alkyl anilines participated in the reaction to provide a wide range of julolidines and lilolidines as the single regio- and diastereoisomers in good to excellent yields.
SDS of cas: 50-84-0. Bye, fridends, I hope you can learn more about C7H4Cl2O2, If you have any questions, you can browse other blog as well. See you lster.
