New mono- and disubstituted pyrido[3,2-d]pyrimidines were synthesized starting from the corresponding 2,4-dichloro derivative through SNAr and palladium-catalyzed reactions. SNAr and palladium-catalyzed hydro-deshalogenation occurred selectively at position C-4. Further Suzuki cross-coupling led to C-2 and C-2,4 mono- and disubstituted compounds.
新合成了单取代和双取代的吡啶[3,2-d]嘧啶,从相应的2,4-二氯衍生物出发,通过SNAr和钯催化反应。SNAr和钯催化的氢脱卤反应选择性地发生在C-4位。进一步的铃木交叉偶联反应生成了C-2和C-2,4的单取代和双取代化合物。
