Seven new compounds, that are isosteric with phosphonate compounds on the basis of structure and charge distribution, have been synthesized. These compounds could be important in the design and synthesis of hapten molecules for catalytic antibodies. Mass spectrometric data for these compounds were o
## Abstract __N__(Pyrimidinβ2βyl)βglycine, βalanine and βphenylalanine (1β3) and their methyl esters (4β6) were investigated using electron impact (EI) mass Spectrometry. The results showed that EIβinduced decomposition occurs on the carboxylic group or involves the loss of R~2~OH. In contrast to e
