α-Thymidine (4) was synthesized from thymidine (1) in 3 steps in 36% overall yield without using chro-matography and with the possibility of increasing the yield to 85% by reusing the remaining α,β-mixture. 1-(2-Deoxy-3,5-di-O-p-toluoyl-α-D-erythro-pentofuranosyl)thymine (3) was further converted to 1-(2-deoxy-α-D-erythro-pentofuranosyl)-5-methylcytosine (5).
从胸腺嘧啶(1)分三步合成α-胸腺嘧啶(4),总收率36%,无需使用色谱法,并且有可能通过重用剩余的α,β-混合物将收率提高至85%。1-(2-脱氧-3,5-二-运算甲苯甲酰-α-D-赤式-pentofuranosyl)胸腺嘧啶(3)进一步转化为1-(2-脱氧-α-D-赤式-pentofuranosyl)-5- -甲基胞嘧啶(5)。
