A series of 3-aminocyclohex-2-enones were reacted with indane-1,2,3-trione monohydrate (ninhydrin) yielding 4b,9b-dihydroxyindeno[1,2-b]indoles that were deoxygenated to indeno[1,2-b]indoles.

shown to be safer alternatives, the most notable was methyl 4-[(p-bromophenyl)amino]-6-methyl-2-oxocyclohex-3-en-1-oate, 13. Compound 13 had an ip ED50 of 4 mg/kg in the rat and a TD50 of 269 mg/kg, providing a protective index (TD50/ED50) of > 67. By variation in the ring size, additional aromatic substitutions and the synthesis of acyclic analogs, these newer compounds provide a more definitive insight

A comparison of enaminones from various unsubstituted and p-substituted benzamides to the analogous benzylamines has been undertaken with the aim of elucidating the essential structural parameters necessary for anticonvulsantactivity. Initial studies on methyl 4-N-(benzylamino)-6-methyl-2-oxocyclohex-3-en-1-oate, 3a, 3-N-(benzylamino)cyclohex-2-en-1-one, 3p, and 5,5-dimethyl-3-N-(benzylamino)-cyclohex-2-en-1-one
The present invention relates to substituted spirocyclic derivatives having the general formula: ##STR1## wherein the dotted line represents a carbon-carbon double bond or a carbon-carbon single bond, wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 are each the same or different, hydrogen or lower alkyl, wherein Z is one of the following: ##STR2## wherein R.sub.7 is either hydrogen or lower alkyl, wherein R.sub.8 and R.sub.9 are each lower alkyl; their methods of preparation and their use as odor-modifying ingredients in perfumes and perfumed products, and as flavor-modifying ingredients in the flavoring of foodstuffs and tobacco products.

pentylenetetrazol, bicuculline, and picrotoxin on isoxazole 10 were all negative, leading to an unknown mechanism of action. X-ray diffraction patterns of a representative of the 3-amino series (isoxazoles 6-11) unequivocally display the existence of intramolecular hydrogen bonding of the nitrogen to the vinylic proton in the cyclohexene ring, providing a pseudo three ring structure which was also shown previously
