Question
Humans lack an enzyme that oxidizes an L-configured example of this moiety, which then spontaneously converts into an enediol (“een-diol”) form. One of these moieties is bound to cyclopentane in a compound secreted by Nepeta plants that leads to the attractive qualities of catnip. Most aldosterone antagonists are in a class of steroids named for this moiety, which is found at the 17-alpha carbon in a spiro position. Vibrio fischeri uses N-acyl (*) homoserine examples of these compounds as autoinducers in quorum sensing. Large examples of this functional group are found in a class of antibiotics that bind to the 50S subunit of the bacterial ribosome, such as erythromycin. Vitamin C contains a 5-membered example of this functional group similar to furan. These single-ring compounds are formed in intermolecular Fischer reactions. For 10 points, name these cyclic esters. ■END■
