A Practical Method for the Synthesis of Highly Enantioenriched trans-1,2-Amino Alcohols
摘要:
A highly enantioselective addition of phenyl carbamate to meso-epoxides has been developed to efficiently generate protected trans-1,2-amino alcohols. This transformation is promoted by an oligomeric (salen)Co-OTf catalyst and has been used to prepare two useful 2-aminocycloalkanol hydrochlorides in enantiopure form on a multigram scale from commercially available starting materials.

The present invention provides novel (meth)acrylic and (meth)acrylamide monomers and polymers produced from those monomers. The monomers of the invention each include only a single vinyl functionality and at least one non-vinyl functionality that can be varied to achieve desired monomer/polymer properties. The invention additionally provides methods of producing polymers from these mono-vinyl monomers.
