The synthesis of a novel spiro-nucleotide, in which the C(4′) and the C(5′) of a nucleotide are connected by an additional ethylene bridge, is reported. The γ-torsional angle of the resulting novel nucleotides is in the region of the one observed in natural double stranded DNA.
报告了一种新型螺核苷酸的合成,其中核苷酸的 C(4′)和 C(5′)通过一个额外的乙烯桥连接。由此产生的新型核苷酸的δ扭转角与在天然双链 DNA 中观察到的δ扭转角相同。
