A practical synthetic method for the direct synthesis of unsymmetrically substituted ureas from N-Alloc-, N-Cbz-, and N-Boc-protected amines is described. In this study, efficient direct conversion of the Alloc-, Cbz-, and Boc-carbamate compounds to ureas was achieved in the presence of DABAL-Me3, an air stable and easily handled reagent. Using this reaction method, both protected aromatic and aliphatic

The sandwich complex [Cp*Ru(eta(6)-pyrene)]-PF6 (Cp* = eta*-C-5(CH3)(5)) serves as a photoactivatable catalyst for the conversion of N-allylcarbamates into their amines in the presence of thiophenol under biorelevant conditions (water, air, plus aliphatic thiols) and even in mammalian cells. This new phototriggered substrate/catalyst pair points towards applications in chemical biology and medicinal chemistry where signal amplification is combined with spacial and temporal control.
