rate-determining step being formation of the tetrahedral intermediate. These model studies suggest that the phenyldimethylacetamide system could be developed as a prodrug system for the bioreductively-triggered release of amines. Further substantial rate enhancements appear possible by alterations in the geometry of the system, whereas substitution of electron-withdrawing groups (required to raise the
