Popis: | Compounds of the novel 7,10a-methanocycloocta[c,d]indazole ring-system 5, 7 are obtained by the action of hydrazines on 1-chloro(or hydroxy)diisophor-2,7-en-3-ones 1–3. Their formulation agrees with their origin and their chemical and spectral characteristics. Analogous syntheses of two comparable ring-systems include the production of a substituted 7,10a-methanocycloocta[g,h][2,1]benzisoxazole 10 by a facile cyclodehydration of the oxime of diisophorone 9a, and that of the indole-analogue 13 by the action of aniline on diisophorone-1-carboxylic acid 11. |
