5-n-Alkylcycloalkane[d]pyrazolo[3,4-b]pyridines were prepared by a microwave-assisted cyclocondensation reaction between 5-aminopyrazoles and cyclic ketones under solvent-free conditions and catalyzed by iodine. This procedure provides a simple one-step and environmentally friendly methodology with good yields for the synthesis of these compounds.
5- Ñ -烷基环烷[ d ]吡唑并[3,4- b由无溶剂的条件下,5-氨基吡唑和环状酮类之间的微波辅助的反应环化缩合制备并通过碘催化]吡啶。该步骤为合成这些化合物提供了简单的一步式方法,并且对环境友好,并且收率很高。
