The synthesis of steroidal derivatives containing [1,2,4]triazolo[1,5-a]pyrimidine derived from progesterone is described. The Claisen condensations of Δ1,4-pregnadien-3,20-dione and 4-chloro-Δ1,4-pregnadien-3,20-dione with dimethyl oxalate afforded 21-methoxalylpregn-1,4-diene-3,20-dione and 4-chloro-21-methoxalylpregn-1,4-diene-3,20-dione, respectively. Furthermore, the reactions of these compounds
描述了含有衍生自孕酮的 [1,2,4] 三唑并 [1,5-a] 嘧啶的甾体衍生物的合成。Δ1,4-孕二烯-3,20-二酮和4-氯-Δ1,4-孕二烯-3,20-二酮与草酸二甲酯的克莱森缩合得到21-methoxalylpregn-1,4-diene-3,20-二酮和 4-chloro-21-methoxalylpregn-1,4-diene-3,20-dione,分别。此外,这些化合物与 3-氨基-1,2,4-三唑的反应产生了相应的 [1,2,4] 三唑并 [1,5-a] 嘧啶衍生物。新合成的化合物通过硫罗丹明 B 测定在体外评估对 HeLa 和 MCF-7 细胞的抗增殖活性。
