摘要:Novel l-acyl-3-amino-4-hydroxymethylpyiÏ„olidine derivatives useful as PNA synthons optionally having protecting groups suitable of removal under mild conditions are disclosed having the formula (E) wherein: R1 is H or R-C(=O), wherein R is straight or branched alkyl, aryl, substituted aryl including from 1 to 5 heteroatoms, a heterocyclic group including from 1 to 3 heteroatoms; R2 is H, a linker bonded to a solid support, or R6-0-C(=0), wherein R6 is an alkyl or substituted alkyl group having a tertiary carbon atom bonded to the oxygen, CHn-Arm-n wherein n is 1 or 2 and m is 2 or 3 and Ar is aryl or substituted aryl, and R3 is a nucleobase selected from thymine I, cytosine II, adenine III, guanine IV, uracil V, xanthine VI and hypoxanthine VII, a derivative of said nucleobases I-VII protected at the reactive functionalities NH2 or imidic NH, a deazacarbocyclic derivative of said nucleobases I-VII optionally protected at the reactive functionality NH2. Also disclosed are novel intermediates useful for the preparation of the aforementioned PNA synthons, as well as to methods for preparing the intermediates and the final synthons. The latter can be useful in the synthesis of peptide nucleic acids (PNAs) and other oligomers such as PNA-DNA chimeras, and may be used in automated synthesizers.
