chiral resolution - 2024 PLAYTIME

Question

Answer some questions about Mosher’s acid, for 10 points each:

[10h] Mosher’s acid is used as a reagent for this process. In another technique, cyclodextrin and amylose cellulose are used as the stationary phase in order to perform this process.

ANSWER: chiral resolution [or enantiomeric resolution or optical resolution; accept chiral derivatization or chiral chromatography; prompt on derivatization or chromatography; prompt on resolution]

[10e] Mosher’s acid is also used to convert alcohols to this functional group. This functional group with the formula RCOOR’ (“R-C-O-O-R prime”) is found in many sweet-smelling chemicals.

ANSWER: esters

[10m] After using Mosher’s acid, this technique can be used to determine which diastereomers are present in a solution. Deuterated solvents like TMS and CDCl3 are used for this technique.

ANSWER: NMR spectroscopy [or nuclear magnetic resonance; accept proton NMR or carbon NMR]
