into a range of 7-indolyl chalcones 13 by reaction with aryl aldehydes under basic conditions. Oxidation of the chalcones 13 with alkaline hydrogen peroxide gave the isolable epoxides 14, which were cyclized with further base treatment into the indole flavonols, or 5-hydroxy-6-oxopyrroloquinolines 15. The related compounds 25 and 26, examples of indole flavanones and flavones, respectively, were also
通过在碱性条件下与芳基醛反应,将7-乙酰基-4,6-二甲氧基-3-苯基吲哚10转化为一系列7-吲哚基查耳酮13。用碱性过氧化氢氧化查耳酮13,得到可分离的环氧化物14,将其通过进一步的碱处理环化为吲哚黄酮醇或5-羟基-6-氧代吡咯并喹啉15。相关化合物25和26,吲哚黄烷酮和黄酮的实例。 ,也分别合成。黄酮类和吲哚类黄酮之间的紫外光谱比较进行了讨论。
