Peptide nucleic acid oligonucleotide conjugates are attracting immense interest currently because of their use in the biomedical and diagnostic field as antigene and molecular sensors. The efficient PNA synthesis methods can reduce their cost and may increase availability for their wider use. Here we described afacile synthesis of the peptide nucleic acid monomer N-(Boc-Aminoethylglycin)thymine Ethyl Ester [Ethyl2-(N-(2-((tert-butoxycarbonyl)amino)ethyl)-2-(5-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamido) acetate]. The monomer N-(Boc-Aeg)thymine Ethyl Ester has been prepared in a good yield (96%) by highly efficient procedure involving direct coupling of nucleobase thymine with the backbone Ethyl N-(Bocaminoethyl)-N-(chloroacetyl)glycinate, which was prepared from the reaction of Ethyl N-[(2-Boc-amino)-ethyl]glycinate with chlroacetylchloride. The key intermediate Ethyl N-[(2-Boc-amino)-ethyl]glycinate involved in the synthesis has been prepared via a scalable and cost-effective route with a yield of (98%). The thyminyl PNA monomer was reported to be used in various synthetic applications, and our cost-effective, highly scalable method of synthesis will expand its wider use.
