The mass spectral fragmentation of 4‐isoxazolyl‐1,4‐dihydropyridines has been examined with the aid of linked metastable scanning. Three prominent pathways involve (i) O‐N bond cleavage of the isoxazole followed by the loss of R2CN, (ii) loss of carboalkoxy from the 3‐ and/or 5‐ position of the dihydropyridine and, (iii) loss of the 4‐isoxazolyl‐substituent.
