A series of N-1-alkylated 6-benzyluracil-5-carboxylic esters 4a-h were synthesized by reacting imines of 3-oxo-4-phenyl-butyrates with N-(chlorocarbonyl) isocyanate. An N-1-(4-methoxy-benzyl) group could be removed in a dealkylation reaction to give the ethyl and allyl esters 5a and 5b, respectively. They were N-1-alkylated with chloromethyl ethyl ether or dialloxymethane. Unfortunately no biological

A ruthenium complex, Cp*Ru(bipyridyl)CI, has been developed as a catalyst for the first regioselective tandem Michael addition-allylic alkylation of activated Michael acceptors. The net transformation is the decarboxylative insertion of Michael acceptors into allyl beta-ketoesters.
