Abstract
Condensation of 1,3,5-tri(tert-butyl)-1,3,5-triazacyclohexane with acetone gave 3,7-di(tert-butyl)-1,5-bis[(tert-butylamino)methyl]bispidin-9-one. Reactions with ethyl methyl ketone and other ketones of the formula RCH2COCH3 yielded 5-R-3,7-di(tert-butyl)-1-[(tert-butylamino)methyl]bispidin-9-ones, while reactions with diethyl ketone and other symmetrical ketones of the formula RCH2COCH2R afforded 1,5-R-3,7-di(tert-butyl)bispidin-9-ones.
