Mecamylamine - Chemistry
... and shown in the reaction scheme above, began with racemic camphene ... Each of these geometrical isomers would be racemic because the starting camphene was racemic ... In practice, only one racemic geometrical isomer, believed to be the exo-isomer on theoretical grounds, was isolated from the reaction, and this substance was given the name "mecamylamine".Racemic ...
Stridor - Treatments
... Use of nebulized racemic adrenaline epinephrine (0.5 to 0.75 ml of 2.25% racemic epinephrine added to 2.5 to 3 ml of normal saline) in cases where airway edema may be the cause of the stridor ... in a dose not exceeding 3 mg/kg may also be used, but not together with racemic adrenaline.) Use of dexamethasone (Decadron) 4–8 mg IV q 8 - 12 h in cases where airway edema ...
Pfeiffer Effect
... active compound influences the optical rotation of a racemic mixture of a second compound ... Racemic mixtures do not rotate plane polarized light, but the equilibrium concentration of the two enantiomers can shift from unity in the presence of a strongly interacting chiral species ... when crystals of sodium chlorate, which are chiral and colourless, were stained with a racemic dye ...
Chiral Resolution - Chiral Resolving Agents
... Derivatization of racemic compounds is possible with optically pure reagents forming pairs of diastereomers which can be separated by conventional techniques in ... The method was introduced (again) by Louis Pasteur in 1853 by resolving racemic tartaric acid with optically active (+)-cinchotoxine ... In one of its steps the racemic alcohol 1 is dissolved in a mixture of toluene and methanol to which solution is added optically active (S)-mandelic acid 3 ...
Galanthamine Total Synthesis - Outline
... In 1962 racemic galanthamine and epi-galanthamine were prepared by organic reduction of racemic narwedine by D ... Racemic narwedine was treated with 0.01 equivalent of (+)-galanthamine resulting in a 76% yield ... Narwedine is a racemic conglomerate allowing the isolation of the S,S enantiomer from the R,R enantiomer by simple crystallization ...
