摘要： A method is disclosed for preparing novel purine PNA synthons having protecting groups which may be removed under mild conditions. The purine PNA synthons generally are prepared by coupling purine derivatives having carbamate protection to a protected N-(2-aminoethyl)-glycine backbone. By a method of this invention, purine PNA synthons may have orthogonal protection of the carbamate protected purine and the protected backbone. The purine 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. In practicing methods of the invention, novel compositions of matter also are disclosed. For example, disclosed herein are an adenine PNA synthon having the following formula: ##STR1## and a guanine PNA synthon having the following formula: ##STR2##

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.

摘要： Method for production of 2'-O-derivatized uridine and cytosine RNA synthons comprising derivatizing the 2'-hydroxyl group of a partially protected cytosine ribonucleoside to preferentially produce a partially protected 2'-O-derivatized nucleoside, which is then either (1) reacted at the 3'-hydroxyl group to produce a 2'-O-derivatized cytosine RNA synthon, or (2) reacted with a hydroxide source to produce a uridine nucleobase by deamination, thereby producing a partially protected 2'-O-derivatized uridine ribonucleoside which can be reacted at its 3'-hydroxyl group to produce a uridine RNA synthon.
