Synthesis of locked cyclohexene and cyclohexane nucleic acids (LCeNA and LCNA) with modofoed adenosine units
2015
Abstract
We describe here the preparation of conformationally locked cyclohexane nucleic acids designed as hybrids between locked nucleic acids (LNAs) and cyclohexene nucleic acids (CeNAs), both of which excel in hybridization with complementary RNAs. We have accomplished the synthesis of these adenine derivatives starting from a simple ketoester and installed all four chiral centres by means of total synthesis.
The acquired monomers were incorporated into nonamer oligonucleotides.
