An enantioselective synergistic cascade cyclopropanation/NHC catalyzed ring opening has been reported. DFT calculations have been performed to confirm the mechanism.
A new ring-opening polymerization mechanism is unveiled based on synergistic catalysis involving Brønsted and Lewis acid centers in a coordination framework.
An enantioselective ring-opening formal [3+2]-cycloaddition of spirovinylcyclopropyl oxindoles with enals via synergistic catalysis of palladium(0) and chiral organocatalyst has been developed, affording spirooxindoles bearing four contiguous stereocenters in good yields...
Amino-functional polyethers have emerged as a new class of “smart”, i.e. pH- and thermoresponsive materials. This review article summarizes the synthesis and applications of these materials, obtained from ring-opening of suitable epoxide monomers.
Synergistic catalysis: enantioselective cyclopropanation of alkylidene benzoxazoles by Pd(ii) and secondary amine catalysis. Scope, limitations and mechanistic insight
