A mixture that has equal amount of enantiomers is commonly known as racemic mixture. Enantiomers have non-superimposable mirror images of one another and therefore; they rotate the plane of polarized light in opposite but equal direction. The racemic mixture is optically inactive in nature.

- Answer the following questions about atomoxetine, a drug used to treatattention deficit hyperactivity disorder (ADHD). a.) What amides can be reduced to form atomoxetine?b.) What starting materials can be used to form atomoxetine by reductiveamination? Draw all possible methods.c.) What products are formed by Hofmann elimination of atomoxetine?arrow_forwardFlexibilene is a terpene isolated from Sinularia flexibilis, a soft coralfound in the Indian Ocean. Draw a stepwise mechanism for the formationof flexibilene from farnesyl diphosphate and isopentenyl diphosphate.What is unusual about the cyclization that forms the 15-membered ringof flexibilene?arrow_forwardExplain why the pKa of a hydrogen bonded to the sp3 carbon of propene is greater (pKa = 42) than that of any of the carbon acids but is less than the pKa of an alkane (pKa > 60).arrow_forward
- Nabumetone is a pain reliever and anti-inammatory agent sold under the brand name of Relafen.a. Write out a synthesis of nabumetone from ethyl acetoacetate.b. What ketone and alkyl halide are needed to synthesize nabumetone by direct enolate alkylation?arrow_forwardβ-Vetivone is isolated from vetiver, a perennial grass that yields a variety of compounds used in traditional eastern medicine, pest control, and fragrance. In one synthesis, ketone A is converted to β-vetivone by a two-step process:Michael reaction, followed by intramolecular aldol reaction. (a) What Michael acceptor is needed for the conjugate addition? (See Problem 23.61 for another method to form the bicyclic ring system of β-vetivone.) (b) Draw a stepwise mechanism for the aldol reaction, which forms the six-membered ring.arrow_forwardFlexibilene is a terpene isolated from Sinularia exibilis, a soft coral found in the Indian Ocean. Draw a stepwise mechanism for the formation of exibilene from farnesyl diphosphate and isopentenyl diphosphate. What is unusualabout the cyclization that forms the 15-membered ring of exibilene?arrow_forward
