We investigated the stereoselective coupling of thymine with sulfoxides derived from meso-thiolane-3,4-diol via the Pummerer reaction. The introduction of 2,4-dimethoxybenzoyl groups to the hydroxyl groups of meso-thiolane-3,4-diol-1-oxide was effective to afford (2R∗, 3R∗, 4S∗)-1-[3,4-di-O-(2,4-dimethoxybenzoyl)thiolane-3,4-diol-2-yl]thymine stereoselectively.
我们研究了胸腺嘧啶的立体选择性耦合与衍生自亚砜内消旋-thiolane -3,4-二醇经由Pummerer重反应。到的羟基基团的引入2,4-二甲氧基苯甲酰基团的内消旋-thiolane -3,4-二醇-1-氧化物是有效的,得到(2 - [R *,3 - [R *,4小号* )-1- [3,立体选择性地有4-二-O-(2,4-二甲氧基苯甲酰基)硫杂环戊烷-3,4-二醇-2-基]胸腺嘧啶。
