<p>Tert-butyl (2S)-2-aminohexanoate is an intermediate that is used in the synthesis of glycine by the reaction of benzyl bromide and tert-butyl amine. The stereospecifically incorporated tert-butyl group has a high degree of enantioselectivity, which makes this intermediate useful in the synthesis of glycine. Tert-butyl (2S)-2-aminohexanoate can be synthesized using lithium diisopropylamide and a tertiary amine as an alkylating agent.</p>

<p>2-Bromo-3,3,3-trifluoro-1-propene is a chemical compound that has been synthesized in an asymmetric reaction. The reactant is bromopropane and the product is 2,2,2-trifluoropropene. The methylene group on the propene molecule is activated by the nucleophilic attack of a fluoride ion from hydrogen fluoride to form a cavity with a highly strained bond. The kinetic study of this reaction revealed that the activation energy for the reaction is 42 kJ/mol. Palladium-catalyzed coupling reactions are catalyzed by palladium and require nonpolar solvents such as toluene or dichloromethane. This type of reaction has been shown to be exothermic with an isolated yield of 1%.</p>
