c)
Interpretation:
How to carry out the transformation shown is to be stated.
Concept introduction:
The carboxylic acid or ester or the carbonyl group in aldehydes and ketones can be reduced without affecting the double bonds in the side chain and in the aromatic ring using LiAlH4 in ether. The alcohol can be converted in to a bromide by treating with PBr3. The bromo compound when treated with NaSH will yield the thiol required,
To state:

- 9) How would you carry out the following transformation? More than one step may be required, write the reactions. H3C CH 3 H3C ? H3C CH3 OH H H3C H "ОН 10) How would you synthesize the following compound from cyclohexanone? More than one step may be required, write the reactions. CH 3arrow_forwardPlease help with part D attached:arrow_forwardPropose a synthesis to carry out the following transformationarrow_forward
- The reaction of an alkene with diazomethane forms a cyclopropane ring. Propose a mechanism for the reaction.arrow_forwardNonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.arrow_forwardA step in a synthesis of PGE1 (prostaglandin E1, alprostadil) is the reaction of a trisubstituted cyclohexene with bromine to form a bromolactone. Propose a mechanism for formation of this bromolactone and account for the observed stereochemistry of each substituent on the cyclohexane ring. Alprostadil is used as a temporary therapy for infants born with congenital heart defects that restrict pulmonary blood flow. It brings about dilation of the ductus arteriosus, which in turn increases blood flow in the lungs and blood oxygenation.arrow_forward
- Show how the following compound can be synthesized from benzene:arrow_forwardPropose a possible reaction mechanism for the following transformation. Draw out the steps with the correct reaction arrows.arrow_forwardC. How would you synthesize the given target compound in multistep syntheses? 2 НО CO₂H CH3arrow_forward
