ABSTRACT OF THE DISCLOSURE: Pinanes substituted by a group X in the 3-position which group is formyl, carboxylic acid, carboxylic acid chloride, carboxylic acid amide, hydroxymethyl or aminomethyl substituted in a specific manner at the nitrogen, the optical isomers of these compounds and a process for their manufacture by hydro- formylation of .alpha.-pinene in the presence of rhodium catalysts, and conversion of the 3-formylpinane first produced into the above derivatives by conventional methods. Because of their functional groups X, the pinanes according to the invention are valuable agents for resolving racemates, bearing a complementary group Y which reacts with X, into their enantiomers.
