The chiral monoaza-15-crown-5 type lariat ethers 1 and 2 derived from a-D-glucose and from D-mannitol, respectively, have been applied as phase transfer catalysts in the enantioselective Michael addition of 2-nitropropane to aromatic 3b-c and heteroaromatic 3d-h chalcone analogues. Among the catalys
