Aziridines are heterocycles that contain an N atom in a three-membered ring. 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 Tamiu, 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.
An unknown compound A of molecular formula C10H18O reacts with H2SO4 to form two compounds (B and C)of molecular formula C10H16. B and C both react with H2 in the presence of Pd-C to form decalin. Ozonolysis of B forms D, and ozonolysis of C forms a diketone E of molecular formula C10H16O2. Identify the structures of compounds A, B, C, and E.
Ibufenac, a para-disubstituted arene with the structure HO2CCH2C6H4CH2CH(CH3)2, is a much more potent analgesic than aspirin, but it was never sold commercially because it caused liver toxicity in some clinical trials. Devise a synthesis of ibufenac from benzene and organic halides having fewer than five carbons.
