The design and facile synthesis of novel chiral piperidine PNA from naturally occurring 4-hydroxy-L-proline is reported. The stereospecific ring-expansion reaction to get six-membered piperidine derivative from 5-membered pyrrolidine derivative is exploited for this synthesis. The resulting conformationally constrained PNA is utilized for the synthesis of PNA mixmers and the concept is substantiated
