The reactions of (arylmethylene)isoxazol-5-ones 1 with pyridinium ylides 2 lead to the diastereoselective formation of olates 4. The reasons for the favored Michael addition and the unsuccessful subsequent cyclization to fused O-heterocycles are discussed on the basis of X-ray analysis as well as 1H-NMR and chemical evidences.
