Abstract:
Benzene-glycol nucleic acid-DNA chimeras form thermally and thermodynamically stable duplexes with complementary RNAs, and have base-discriminating abilities. This unit describes the synthesis of four nucleoside analogs, an adenine, cytosine, thymine, and guanine analogs with base-benzene-glycol structure. The synthesis starts with conversion of (S)-mandelic acid in arylboronic acid derivative, common intermediate. Nucleobase coupling of the intermediate and phosphitylation afford to phosphoroamidite units. © 2017 by John Wiley & Sons, Inc.

Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.
