A preparative route is proposed for the synthesis of the novel heterocyclic systems 7-oxo- and 1,2,7-trioxo-1,2-dihydropyrano[3,2-e]indole using classical Fischer and Sandmeyer methods respectively. We have studied various conditions for cyclization of the starting coumarin 6-isonitrosoacetamide and the methyl or ethyl pyruvate 6-coumarinylhydrazones. The syn- and anti-form ratio of the latter and the structure of all of the synthesized compounds were determined using spectroscopic data analysis. [ABSTRACT FROM AUTHOR] |
