专利号:US-6172226-B1 优先权日:1993-12-22 标 题:Synthons for the synthesis and deprotection of peptide nucleic acids under mild conditions 发明人:COULL JAMES M; EGHOLM MICHAEL; HODGE RICHARD P; ISMAIL MOHAMED; RAJUR S B 权利人:PERSEPTIVE BIOSYSTEMS INC 摘要:A method is disclosed for preparing novel PNA synthons having protecting groups capable of removal under mild conditions. The PNA synthons are prepared by coupling novel N-substituted nucleobase intermediates having carbamate protection of the exocyclic amino group of the heterocycle to an amino protected backbone or an amino protected backbone ester of the amino acid N-(2-aminoethyl)-glycine. By the method of this invention, the resultant PNA synthons can have orthogonal protection of the carbamate protected nucleobase and the amino protected backbone. The PNA synthons are useful in the synthesis of peptide nucleic acids (PNAs) and other oligomers such as PNA-DNA chimeras, and may be used in automated synthesizers. Novel compositions of matter are also disclosed. In addition, a guanine PNA synthon having selective carbamate protection of the exocyclic 2-amino group with the C6 carbonyl group unprotected is disclosed.

A halogenated derivative compound is used as a dormant species for initiating living radical polymerization. The derivative compound is obtained by halogenating an alcohol compound having a non-conjugated structure or an amine compound having a non-conjugated structure with a halogenating agent capable of halogenating an alcohol or amine. A radical produced by elimination of halogen from the halogenated derivative compound is allowed to react with the unsaturated bond of the monomer. Thus, the monomer, which has a radical-reactive unsaturated bond, is polymerized by living radical polymerization. Preferably, the halogenating agent is a compound (NIS or the like) which also has a function as a catalyst.
