The reduction of a series of α,β-unsaturated ketones has been studied under various experimental conditions, by using β-branched trialkylalanes. Asymmetric induction phenomena are observed when optically active trialkylalanes are used.

The present invention relates to substances and compositions having a physiological cooling effect on the skin and the mucosa of the body, especially of the oral cavity, throat and nose. More in particular, the present invention relates to N-substituted-p-menthane-3-carboxamides represented by the following formula (I):
and esters thereof. These substances are capable of imparting and/or enhancing a physiological cooling effect in a product in which they are incorporated, much more effectively than the heretofore known N-substituted-p-menthane-3-carboxamides.
