2,6-二氯嘌呤核苷的合成工艺研究
Synthesis of 2,6-Dichloroadenosine
【摘要】 以2,6-二氯嘌呤和1,2,3,5-四乙酰核糖为原料,四氯化锡为催化剂,130℃下反应18min,得到中间体2,6-二氯嘌呤-2’,3’,5’-三乙酰基核苷。该中间体在硫酸-甲醇中脱酰基得到2,6-二氯嘌呤核苷,为白色粉状结晶,收率63%,纯度(HPLC)≥99.0%,熔点152 ̄154℃。
【Abstract】 A new method for synthesizing 2,6-dichloroadenosine was reported in the paper. The starting material 2,6-dichloropurine was condensed with 1,2,3,5-tetraacetylribofuranose at 130℃ for 18 minutes to form 2’,3’,5’-triacetyl-2,6-dichloroadenosine,which was deprotected in H2SO4-CH3OH at 0~5℃ to give the target product 2,6-dichloroadenosine as a white crystalline powder. The yield was 63%,purity(HPLC)≥99.0%,and the melting point of the product was 152~154℃.
