PEPTIDE NUCLEIC ACID (PNA) MONOMERS WITH AN ORTHOGONALLY PROTECTED ESTER MOIETY

This application pertains to orthogonally protected esters of peptide nucleic acid (PNA) monomers, which ester groups can be removed under conditions that permit typical backbone and side chain acid- and base-labile protecting groups to remain substantially intact thereby permitting the high yield of PNA monomer carboxylic acids that are suitable for use in PNA oligomer synthesis. Exemplary ester groups include, but are not limited to, 2,2,2-trichloroethyl (TCE), 2,2,2-tribromoethyl (TBE), 2-bromoethyl (2-BE) and 2-iodoethyl groups (2-IE). This invention also pertains to novel methods for the synthesis of Backbone Ester compounds and related Backbone Ester Acid Salts.

Fast and Facile Synthesis of 4-Nitrophenyl 2-Azidoethylcarbamate Derivatives from N-Fmoc-Protected α-Amino Acids as Activated Building Blocks for Urea Moiety-Containing Compound Library

A fast and facile synthesis of a series of 4-nitrophenyl 2-azidoethylcarbamate derivatives as activated urea building blocks was developed. The N-Fmoc-protected 2-aminoethyl mesylates derived from various commercially available N-Fmoc-protected α-amino ac

Efficient synthesis of N-fmoc-aminoalkoxy pentafluorophenyl carbonates: Application for the synthesis of oligopeptidyl carbamates

N-Fmoc-Aminoalkoxy pentafluorophenyl carbonates have been synthesized through the reaction of N-Fmoc-aminoalkoxy carbonyl chloride with pentafluorophenol. The reaction was clean and high yielding, and the products have been fully characterized using infra

Reduction of pentafluorophenyl esters to the corresponding primary alcohols using sodium borohydride

Primary alcohols and chiral N-protected 2-amino alcohols can be obtained in high yields from the reaction of pentafluorophenyl esters of the corresponding carboxylic acids with sodium borohydride in THF under mild conditions. This reductive method is rapid and compatible with various functional groups as well as with the most common N-protective groups Z, Boc and Fmoc.

Synthesis of 9-fluorenylmethoxycarbonyl-protected amino aldehydes

9-Fluorenylmethoxycarbonyl-protected amino aldehydes could be efficiently prepared in good yields by using two methods: (i) NaBH4 reduction of Fmoc-protected mixed anhydrides, followed by the Swern oxidation of the alcohols; and (ii) LiAlH

A facile synthesis of chiral N-protected β-amino alcohols

Chiral N-protected β-amino alcohols are easily obtained by NaBH4 reduction of mixed anhydrides of N-protected α-amino acids in an organic/aqueous medium. The alcohols obtained from side chain or main chain reduction of N-protected aspartic acid are converted in good yields into lactones.
