addition of the intermediates on dibromomaleimide, the so-obtained acyclic adducts being finally photochemically cyclised to the desired analogues. Compounds of the second series were obtained by reacting different 5-substituted-indole-3-glyoxylates with N-Boc-pyrazole-3-acetamide and subsequent photochemical cyclisation of the adducts.
制备了两个系列的海洋生物碱颗粒乌拉地米特和异戊酸拉米地米的区域异构吡唑类似物。第一系列的合成基于不同的5-取代的3-溴吲哚与吡唑的缩合反应,然后在二溴马来酰亚胺上添加中间体,如此获得的无环加合物最终被光化学环化为所需的类似物。通过使不同的5-取代的吲哚-3-乙醛酸酯与N -Boc-吡唑-3-乙酰胺反应,然后对加合物进行光化学环化,获得第二系列的化合物。
