A new carbon–carbon bond cleavage reaction was developed for the efficient synthesis of multisubstituted pyrazolo[1,5-a]pyrimidines. This base induced reaction of 1,3,5-trisubstituted pentane-1,5-diones and substituted pyrazoles afforded good yields of the pyrazolo[1,5-a]pyrimidines.
为了有效合成多取代的吡唑并[1,5- a ]嘧啶,开发了一种新的碳-碳键裂解反应。该碱诱导的1,3,5-三取代戊烷-1,5-二酮与取代的吡唑的反应提供了吡唑并[1,5- a ]嘧啶的良好收率。
