Unprecedentedendo-oxidative cyclometallation and [4 + 3] cycloaddition of diene-vinylcyclopropanes Jun Yang, Pan Zhang, Zeyuan Shen, Yi Zhou, Zhi-Xiang Yu Chem,2023, DOI: 10.1016/j.chempr.2023.01.020 余志祥教授简介: 教育和工作经历 •1987-1991,武汉大学,学士; •1994-1997,北京大学,硕士; ...
A terpene cyclase subsequently catalyses a fragmentation into two reactive intermediates, followed by hydrogen transfers between them and recombination of the fragments by [4 + 3] cycloaddition. This study solves the intricate mechanistic problem of extra methyl group formation in sodorifen ...

Lewis acid-mediated [4+3] cycloadditions using Me2 AlCl,17 Sc(OTf)3,18 and TiCl4 in dichloromethane resulted in complex mixture, probably due to the coordination of the furan to the Lewis acids to deactivate them. On the other hand, Brønsted acid such as trifluoromethanesulfonic acid ...
