87-91-2, Name is (2R,3R)-Diethyl 2,3-dihydroxysuccinate, molecular formula is C8H14O6, COA of Formula: C8H14O6, belongs to chiral-catalyst compound, is a common compound. In a patnet, author is Wang, Xiaonan, once mentioned the new application about 87-91-2.
An efficient enantioselective addition of thiols to acyclic trifluoromethyl ketimines has been established by using a bifunctional squaramide catalyst, which was derived from quinine, and the reaction was completed in 5 to 10 min. The construction of chiral tetrasubstituted carbon centers bearing trifluoromethylatedN,S-ketals has been achieved in high yields (up to 96% yield) with excellent enantioselectivities (up to 99% ee).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 87-91-2 help many people in the next few years. COA of Formula: C8H14O6.
