Two monomers for the syntheses of conformationally restricted peptide nucleic acids were synthesized through a simple procedure, involving an asymmetric 1,3-dipolar cycloaddition chemistry as a key step, from common starting materials in 3 and 5 steps, and 58.8% and 30.5% overall yields, respectively.
