- Synthesis method of hydrogenated limonyl tertiary amine
-
The invention discloses a synthesis method of hydrogenatedlimonyl tertiary amine. Thesynthetic raw materials comprisecitronellol and tetrahydrogeraniol. The method comprises the following steps: takingbrominated products, citronellyl bromide and tetrahydrogeraniyl bromide,of citronellol and tetrahydrogeraniol as raw materials, and heating the citronellyl bromide, the tetrahydrogeraniyl bromide, dimethylamine, diethylamine, di-n-propylamine and morpholine in an organic solvent in a hydrothermal synthesis reaction kettle at 110-135 DEG C for 24-72 hours, and then, performing cooling, filtering and distilling to obtain four types of dihydrolimonyl tertiary amines and four types of tetrahydrolimonyl tertiary amines which are all colorless liquids and have GC purity of more than 95%. The hydrogenated limonyl tertiary amine is an important intermediate for further synthesis of quaternary ammonium salt compounds containing hydrogenated limonyl.

- Rhodium-catalyzed asymmetric synthesis of β-branched esters from allylic amines
-
Allylic amines are converted to chiral, β-branched esters under rhodium catalysis in the presence of alcohol nucleophiles. Allylic amines with aliphatic and aromatic vinylic substituents are converted to ester products with excellent enantioselectivities in all cases. Several alcohol nucleophiles have been utilized in the reaction including 1° and 2° derivatives.
