Several trans- and cis-2-acetyl-3-(substituted-phenyl)-3,3a,4,5-tetrahydro-2H-benzo[g]indazole derivatives have been synthesised via the condensation of the appropriate exocyclic α,β-unsaturated ketones with hydrazine in hot acetic acid, to obtain diastereomeric mixtures of N-acetylated isomers. Structure elucidation was based on their spectral data and the trans–cis stereochemistry using of NOE and
通过适当的环外α,β-缩合合成了几种反式和顺式-2-乙酰基-3-(取代-苯基)-3,3a,4,5-四氢-2H-苯并[g]吲唑衍生物不饱和酮与肼在热乙酸中反应,得到 N-乙酰化异构体的非对映混合物。结构解析基于它们的光谱数据和使用 NOE 和 NOESY 实验的反式-顺式立体化学。对这些衍生物作为β-血红素形成抑制剂进行了生物学测试。
