Application
The purpose of Cyclic-Oligo Bis[(1S,2S)-(-)-1,2-cyclohexanediamino-N,N-bis(3,3-di-t-butylsalicylidene) cobalt(III)triflate]-5,5-bis(2-carboxyethyl)ether is to serve as a versatile oligomeric catalyst in various chemical reactions. It facilitates the hydrolytic kinetic resolution of terminal epoxides under solvent-free conditions, which is crucial for producing enantioenriched compounds. Additionally, it is employed in the synthesis of enantioenriched tetrahydrofurans through the intramolecular openings of oxetanes. Furthermore, this catalyst is instrumental in the enantioselective addition of phenyl carbamate to meso-epoxides, aiming to yield trans-1,2-amino alcohols.
