Abstract

Compounds of the formula where ring B may be further substituted may be prepared by (a) reacting a suitable benzaldehyde derivative with 3,5,5-trimethylcyclohexene-2-one-1 to give a benzal compound which is reduced to the 3,5,5,-trimethyl-6- benzyl-cyclohexanone-1 and then reductively aminated, (b) reacting a benzyl halide with 3,5,5-trimethylcyclohexene and reducing and reductively aminating the product. A sulphonic acid given may be introduced into ring B of the product by sulphonation.
