All of the four nucleobases found in DNA have been incorporated
in their protected form into the 4-position of
N-tert-butoxycarbonyl-L-proline methyl ester with
cis-stereochemistry. An efficient route for the synthesis of
N-tert-butoxycarbonyl-trans-4-hydroxy-D
-proline methyl ester has been developed from which the
enantiomers may be synthesized. In addition an efficient synthesis of
N-tert-butoxycarbonyl-N-(2-hydroxyethyl)glyc
ine methyl ester has been achieved and its hydroxy group replaced with
protected nucleobases using the Mitsunobu reaction
DNA中的所有四种核苷酸碱基均已以其保护形式整合到了N-叔丁氧羰基-L-脯氨酸甲酯的4-位,并保持顺式立体化学结构。从N-叔丁氧羰基-反式-4-羟基-D-脯氨酸甲酯的高效合成路线中,可以制备其对映体。此外,还实现了N-叔丁氧羰基-N-(2-羟乙基)甘氨酸甲酯的高效合成,并通过 Mitsunobu 反应将其羟基替换为保护的核苷酸碱基。
