  Synthesis of 1,4-Disubstituted Pyrazolo[3,4-d]pyrimidines from 4,6-Dichloropyrimidine-5-carboxaldehyde: Insights into Selectivity and Reactivity

  摘要：

  Strategies for carrying out the reaction of 4,6-dichloropyrimidine-5-carboxaldehyde with both aromatic and aliphatic hydrazines to generate 1-substituted 4-chloropyrazolo[3,4-d]pyrimidines in a selective, high-yielding, and operationally simple manner are presented. For aromatic hydrazines, the reaction is performed at a high temperature in the absence of an external base. For aliphatic hydrazines, the reaction proceeds at room temperature in the presence of an external base. The observed selectivity and reactivity trends are rationalized through consideration of the proposed reaction mechanism. The 1-substituted 4-chloropyrazolo[3,4-d]pyrimidine products serve as versatile synthetic intermediates, through further functionalization of the 4-chloride moiety, enabling the rapid generation of a structurally diverse array of 1,4-disubstituted pyrazolo[3,4-d]pyrimidines.

  Strategies for carrying out the reaction of 4,6-dichloropyrimidine-5-carboxaldehyde with various hydrazines to generate 1-substituted 4-chloropyrazolo[3,4-d]pyrimidines in a selective and high-yielding manner are presented. For aromatic hydrazines, the reaction is performed in the absence of an external base, which promotes exclusive hydrazone formation. The hydrazones subsequently cyclize at an elevated temperature to form the desired pyrazolo[3,4-d]pyrimidine products. For aliphatic hydrazines, the reaction sequence proceeds as a single step in the presence of an external base.
