The Mn(OAc)3-promoted C–H phosphonation of 7-deazapurines (pyrrolo[2,3-d]pyrimidines) and 9-deazapurines (pyrrolo[3,2-d]pyrimidines) with diethylphosphite was developed. The reactions occur regioselectively at position 8 both in 7 and 9-deazapurines, leading to new deazapurine-8-phosphonate derivatives, which can be further modified and transformed to 6-(het)aryl-deazapurine derivatives or deprotected
将Mn(OAc)3促进的C-H的7-脱氮嘌呤(吡咯并[2,3膦酸化d ]嘧啶)和9-脱氮嘌呤(吡咯并[3,2- d ]嘧啶)与亚磷酸二乙酯的开发。该反应在7和9-脱氮嘌呤中的8位区域选择性地发生,产生新的脱氮嘌呤-8-膦酸酯衍生物,其可以被进一步修饰并转化为6-(杂)芳基-脱氮嘌呤衍生物或脱保护为游离膦酸。
