  Potential non-steroidal estrogens and antiestrogens, IV Organic azides in heterocyclic synthesis, part 13: Synthesis of aza- and diazacoumestrols via azido derivatives

  摘要：

  4-Chloro-3-aryl-coumarins and quinolones 2 a-e undergo thermolytic ring closure by reaction with sodium azide in refluxing dimethyl formamide to yield indolo[3,2-c]coumarins and indolo[3,2-c]quinolin-6(5H)-ones 6 a-e. In the case of the coumarin 2 a the azido coumarin 5 can be isolated. The mono- and diazacoumestrol-dimethylethers 6 a-c are converted into the coumestrol analogues 7 a-c and their diacetyl derivatives 8 a-c.
