Green synthesis of 6-isothiocyanato-9-benzyl purine
摘要:
以6-氯嘌呤为原料,9-位经苄基保护后,与硫氰酸银合成6-异硫氰基-9-苄基嘌呤化合物,并对其合成条件进行了优化.以甲苯/水(体积比为2∶1)作为溶剂,在110℃下反应24h,相转移催化剂SDBS(十二烷基苯磺酸钠)为1mol的条件下,6-异硫氰基-9-苄基嘌呤的产率达到最高(92%收率).目标化合物的结构经~1 H NMR(核磁共振氢谱)、13 C NMR(核磁共振碳谱)和HRMS(高分辨质谱)表征,证明合成了目标产物.
The 6-isothiocyanato-9-benzyl-purine was obtained from 6-chloro-9-benzyl purine and silver thiocyanate.The synthetic conditions of 6-isothiocyanato-9-benzyl purine were optimized.6-isothiocyanato-9-benzyl purine had a high yield(92%)when the reaction was carried out in the presence of toluene and H_2 O component solvent which the volume ratio was 2∶1 at 110 ℃for 24 hcatalyzed by 1 mol phase transfer catalyst of sodium dodecyl benzene sulfonate(SDBS).The structure of the resulting compounds was characterized by ~1 H NMR,^(13) C NMR and HRMS.The results showed that the structure of the target products were consistent with that of the designed compounds.
