专利号:US-2021171437-A1 优先权日:2017-07-17 标题 :Peptide nucleic acid (pna) monomers with an orthogonally protected ester moiety and novel intermediates and methods related thereto 发明人:COULL JAMES M; GILDEA BRIAN D 权利人:VERA THERAPEUTICS INC 摘要:The present disclosure pertains to peptide nucleic acid (PNA) monomers and oligomers, as well as methods and compositions useful for the preparation of PNA monomer precursors (e.g. PNA Monomer Esters, Backbone Esters and Backbone Ester Acid Salts, as described below) that can be used to prepare PNA monomers wherein said PNA monomers can be used to prepare said PNA oligomers. In some embodiments, the disclosure features sulfonic acid salts of Backbone Ester compounds, which sulfonic acid salts generally tend to be crystalline and can be obtained in reasonably good yield, often without requiring any chromatographic purification of the reaction product of the Backbone Ester synthesis reaction. This disclosure also pertains to novel methods for the synthesis of said Backbone Ester compounds and novel methods for the formation of the related sulfonic acid salts. Exemplary ester groups include, but are not limited to, 2,2,2-trichloroethy-(TCE), 2,2,2-tribromoethyl-(TBE), 2-iodoethyl-groups (2-IE) and 2-bromoethyl-(2-BrE) as the ester group. These particular ester groups can be removed under conditions where both Boc and Fmoc protected amine groups are stable.
