Compounds of the novel 7,10a-methanocyclooctaindazole 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-methanocyclooctabenzisoxazole 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.
