Terreic acid hinders bacterial growth by covalently binding to (and thereby deactivating) the biosynthetic enzyme MurA, which is responsible for synthesizing the bacterial cell wall. In aqueous environments, terreic acid tautomerizes to a more stable enol form. Draw the two most stable enol tautomers of terric acid.

Like epoxides, aziridines are strained and reactive because the 60° bond angles of the three-membered ring deviate greatly from the theoretical tetrahedral bond angle. One step in the synthesis of the drug oseltamivir (trade name Tamiflu, Section 3.2) involves the conversion of amine X to diamine Y, a reaction that occurs by way of an intermediate aziridine. Draw a stepwise mechanism for the conversion of X to Y. Indicate the structure of the aziridine intermediate, and explain the trans stereochemistry of the two amines in Y.arrow_forward
- Verapamil, a coronary artery vasodilator, is used in the treatment of angina caused by insufficient blood flow to cardiac muscle. Even though its effect on coronary vasculature tone was recognized over 30 years ago, only recently has its role as a calcium channel blocker become understood. Following is a retrosynthetic analysis leading to a convergent synthesis; it is convergent because (A) and (B) are made separately and then combined (i.e., the route converges) to give the final product. Convergent syntheses are generally much more efficient than those in which the skeleton is built up stepwise. Q. Two steps are required to convert (D) to (C). The first is treatment of (D) with ethyl chloroformate. What is the product of this first step?
