d-α-Terpineol (1), which is a useful flavor and fragrance compound, has been synthesized from d-limonene by Markovnikov addition using trifluoroacetic acid, followed by hydrolysis in 76% yield with 98% purity.

The first synthesis of aristoquinoline (1), a naturally occurring nicotinic acetylcholine receptor (nAChR) antagonist, was accomplished using two different approaches. Comparison of the synthetic material's spectroscopic data to that of the isolated alkaloid identified a previously misassigned stereogenic center. An evaluation of each enantiomer's activity at the α3β4 nAChR revealed that (+)-1 is significantly more potent than (-)-1. This unexpected finding suggests that naturally occurring 1 possesses the opposite absolute configuration from indole-containing Aristotelia alkaloids.
Hydration of alpha-Pinene to obtain alpha-terpineol, using an ionic liquid as solvent, which is synthesized from a tertiary amine and an inorganic acid

Paragraph 0016-0020, (2021/06/11)
An ionic liquid as a solvent in the hydration reaction of α-pinene to α-terpineol. The ionic liquid is obtained from the reaction of an amine and an inorganic acid. The use of the ionic liquid as solvent favors the selectivity towards the formation of α-terpineol and once the reaction product has been brought to room temperature, the organic phase can be physically separated from the inorganic one by decantation. The inorganic phase contains the ionic liquid, water and reaction catalyst and can be directly reused for a new reaction batch.
