In view of the synthetic and biological interest of pseudoproline (ΨR,RPro)-containing peptides, we have investigated a new strategy to these target compounds, taking into account the existence of the well-known ring–chain tautomerism occurring in

We have shown that condensation of l -cysteine methyl ester ( 8 ) and l -threonine methyl ester ( 11 ) with formaldehyde provides a convenient and efficient access to novel heterocyclic 2:3 adducts. Depending on the amino acid, the condensation leads
