Simple and Efficient Method for N-Boc Protection of Amines Using PEG-400 as a Reaction Medium Under Mild Conditions
摘要:
Simple and efficient method for N-Boc protection of amines using PEG-400 as an ecofriendly reaction medium at room temperature is described. Various aromatic, heteroaromatic, and aliphatic amines were converted to the corresponding N-tert-butyl-carbamates in good to excellent yields in short times.
The disclosure is directed to: (a) phosphacycle ligands; (b) catalyst compositions comprising phosphacycle ligands; and (c) methods of using such phosphacycle ligands and catalyst compositions in bond forming reactions.
