The intramolecular addition of tosylureas to allenes is highly syn-/anti-diastereoselective when employing a palladium or rhodium-based catalytic system and affords 1,3-cyclic ureas. Under palladium catalysis a range of thermodynamic anti-tetrahydropyrimi

Six-membered cyclic sulfamidates are prepared in high yields by treatment of allenic sulfamates with readily available Ph3PAuNTf2. The reaction enables formation of N-substituted quaternary centres in high yields. The relative stereo

Game, set, and match: The first regio- and enantioselective version of the title reaction is described. The chiral catalyst prepared in situ from CrCl 3 and a non-C2-symmetric bis(oxazoline) ligand 1 affords the valuable chiral ss-al
