Synthesis of some imidazolyl-substituted 2-benzylidene indanone derivatives as potent aromatase inhibitors for breast cancer therapy
摘要:
The synthesis and aromatase inhibitory activity of a new series of 2-benzylidene indanones is presented. The imidazolyl-substituted indanones displayed potent aromatase inhibitory activity. The vanilloid-based derivative 2-[4-(3-imidazol-1-ylpropoxy)-3-methoxybenzylidene]-indan-1-one (26) exhibited maximum inhibition of human placental aromatase and was found to be 54 times more potent as compared to aminoglutethimide.

Electronically-controlled diastereoselective synthesis of spirocycles <i>via</i> [4 + 2] cycloaddition of 2-arylidene-1-indenones with benzyne
A one-pot electronically controlled [4 + 2] cycloaddition reaction of in situ generated benzyne with 2-arylidene-1-indenone is unveiled to construct novel spirocyclic frameworks in a regio- and diastereoselective fashion. This protocol features operational simplicity, good functional group tolerance and avoids the use of metal catalysts and external additives. This methodology has extended the synthetic
揭示了原位生成的苯与 2-亚芳基-1-茚酮的单锅电子控制 [4 + 2] 环加成反应,以区域和非对映选择性方式构建新型螺环框架。该协议具有操作简单、良好的官能团耐受性并避免使用金属催化剂和外部添加剂的特点。这种方法扩展了 2-arylidene-1-indenones 的合成应用,可以轻松获得有价值的 10' H -spiro[indene-2,9'-phenanthren]-1(3 H )-ones 并获得高产率。
