The one-pot myrtenol amination was studied over Au (3 wt.%)/ZrO2 catalyst under mixed N-2/H-2 atmosphere (9 bar). The effect of hydrogen addition was explored with the aim to increase selectivity to the target amines. Hydrogen addition timing depending on myrtenol conversion and hydrogenation temperature affected selectivity to the reaction products. Hydrogen addition (1 bar) after almost complete myrtenol conversion at 100 degrees C increased the yield to amine up to 68% preserving C=C bond in the initial myrtenol structure. Hydrogen addition at 180 degrees C irrespective of the myrtenol conversion level provoked reduction of both C=C and C=N bonds with formation of two diastereomers (yield up to 93%), with trans isomer formation being preferred when hydrogen was added at almost complete myrtenol conversion. It was shown, that in the presence of a gold catalyst controlled hydrogenation of competitive C=C and C=N groups can be performed during one-pot alcohol amination by regulation of the reaction conditions.
