The synthesis of the thymidine 2-deoxypolyoxin C analogue 10 from a noncarbohydrate precursor was achieved in 10 steps and 9% yield starting from a chiral gamma,delta-epoxy-beta-hydroxy ester 11 readily available from cis-2-butene-1,4-diol. The main steps concern the stereo- and regioselective opening of the epoxide ring by an azide anion, the stereoselective introduction of the thymine base, and the
由非碳水化合物前体合成胸腺嘧啶2-脱氧多恶菌素C类似物10需10个步骤,产率为9%,从顺式-2-丁烯-1制备的手性γ-δ-环氧-β-羟基酯11开始, 4-二醇。主要步骤涉及叠氮化物阴离子对环氧环的立体和区域选择性开环,胸腺嘧啶碱的立体选择性引入,以及伯醇向最终产物的酸官能度的转化。还研究了另外两种方法。
