The present invention relates to γ-PNA monomers according to Formula I where substituent groups R, R, R, R, R, R, B and P are defined as set forth in the specification. The invention also provides methodology for synthesizing compounds according to Formula I and methodology for synthesizing PNA oligomers that incorporate one or more Formula I monomers. 5. The PNA monomer of claim 1 , wherein{'sub': 1', '2', '2', '2', 'q', '2', '2', '2', 'q', '3', '2', '2', '2', 'q', '2', '3', '2', '2', '2', 'q', '3', '3, 'Ris —CH(OCHCH)OH; —CH(OCHCH)OCH; —CH(OCHCH)OCHCH; or —CH(OCHCH)OC(CH);'}{'sub': '2', 'Ris H;'}{'sub': 3', '4', '5', '6, 'R, R, R, and Reach independently are H;'}P is selected from the group consisting of H, 9-fluorenylmethyloxy carbonyl (Fmoc), tert-butyloxycarbonyl (Boc), benzyloxycarbonyl (Cbz), tosylate (Ts), benzyl (Bn), allyloxycarbonyl (alloc), trityl (Trt), dimethoxytrityl (DMT), and monomethoxytrityl (MMT);n is 0, 1, or 2; andq is 1, 2, 3, 4, or 5.6. The PNA monomer of claim 5 , wherein P is H; n is 1; and q is 1 claim 5 , 2 claim 5 , or 3.7. The PNA monomer of claim 1 , wherein Rand Rare H; Ris H or —CH; Ris H or —CH; n is 1; and q is 1 claim 1 , 2 or 3.8. The PNA monomer of claim 7 , wherein P is 9-fluorenylmethyloxy carbonyl (Fmoc) or tert-butyloxycarbonyl (Boc).11. A PNA oligomer comprising the PNA monomer of .15. The PNA oligomer of claim 11 , wherein{'sub': 1', '2', '2', '2', 'q', '2', '2', '2', 'q', '3', '2', '2', '2', 'q', '2', '3', '2', '2', '2', 'q', '3', '3, 'Ris —CH(OCHCH)OH; —CH(OCHCH)OCH; —CH(OCHCH)OCHCH; or —CH(OCHCH)OC(CH);'}{'sub': '2', 'Ris H;'}{'sub': 3', '4', '5', '6, 'R, R, R, and Reach independently are H;'}P is selected from the group consisting of H, 9-fluorenylmethyloxy carbonyl (Fmoc), tert-butyloxycarbonyl (Boc), benzyloxycarbonyl (Cbz), tosylate (Ts), benzyl (Bn), allyloxycarbonyl (alloc), trityl (Trt), dimethoxytrityl (DMT), and monomethoxytrityl (MMT);n is 0, 1, or 2; andq is 1, 2, 3, 4, or 5.16. The PNA oligomer of claim 11 , ...
