Examples of Using ENANTIOPURE in a Sentence

• the specific rotation of enantiopure 1-phenylethanol can be enhanced by the addition of achiral acetophenone as an impurity.
• Homochirality can also refer to enantiopure substances in which all the constituents are the same enantiomer (a right-handed or left-handed version of an atom or molecule), but some sources discourage this use of the term.
• A partly enantiopure variant of allethrin I, consisting of only two stereoisomers in an approximate ratio of 1:1, is called bioallethrin.
• Chemically, armodafinil is the enantiopure (R)-(–)-enantiomer of the racemic mixture modafinil (brand name Provigil).
• For example, an enantiopure poly (isocyanate) derivative has been shown to form ordered arrays of squashed donut structures.
• Even for a product which can be attained through an asymmetric catalytic or auxiliary-based route, the racemate may be significantly less expensive than the enantiopure material, resulting in heightened cost-effectiveness even with the inherent "loss" of 50% of the material.
• Originally synthesized in 1993, several groups have designed novel and creative methods of synthesizing enantiopure solenopsin and other alkaloidal components of ant venom.
• These diastereomers may be separated by column chromatography and hydrolyzed to obtain each enantiomer of Pirkle's alcohol in enantiopure form.
• Levoamphetamine was first introduced in the form of racemic amphetamine under the brand name Benzedrine in 1935 and as an enantiopure drug under the brand name Cydril in the 1970s.
• Enantiopure tert-butanesulfinamide can be prepared by enantioselective oxidation of inexpensive di-tert-butyl disulfide to the thiosulfinate followed by disulfide bond cleavage by lithium amide.
• Enantiopure p-toluene-sulfinyl imines arise by the reaction of the commercially available Andersen reagent (menthyl p-toluenesulfinate) with metallo-ketimines but is limited to ketone derived N-sulfinyl imines.
