In a method developed by Alice Ball, compounds containing this functional group (15[2])are synthesized from chaulmoogra oil and used to treat leprosy. In one reaction, the coupling of two instances of this functional group into an acyloin is catalyzed by elemental sodium. This non-nitrogen-containing functional group is the main moiety formed during a Steglich reaction. IR spectra (15[1])of this functional group usually display two or more peaks around 1000 to 1300 inverse centimeters and a strong peak near (*) 1730 inverse centimeters. This functional group (10[1])appears in the ring of a lactone. (-5[5])This functional group is generated (10[1])from the reflux of an alcohol and carboxylic acid in a reaction named (-5[1])after Emil Fischer. (10[3])For (10[1])10 points, (10[1])compounds (10[1])containing what (10[1])functional group with general formula RCOOR are known for their (-5[1])fragrant aromas? (10[2])■END■ (10[4]0[1])
