General description
Chiral BINAP-AuTFA- and chiral BINAP-AgTFA (TFA = trifluoroacetate anion) -promoted catalytic enantioselective 1,3-dipolar cycloadditions of iminoglycinates with trans-1,2-bis(phenylsulfonyl)ethylene were studied.
Application
trans-1,2-Bis(phenylsulfonyl)ethylene was used in total synthesis of (+)-7-deoxypancratistatin.
