Chondrocole A is a marine natural product isolated from red seaweed that grows in regions of heavy surf in the Pacific Ocean. (a) Predict the solubility of chondrocole A in water and CH2Cl2. (b) Locate the stereogenic centers and label each as R or S. (c) Draw a stereoisomer and a constitutional isomer of chondrocole A.

Phenylethanol can be oxidised to phenylethanal or phenylethanoic acid, depending on the reagents used (both the alcohol and the aldehyde are of interest for their antimicrobial properties, while the acid is used to treat type II hyperammonemia): A (a) (b) (c) CoH,CH,CHO phenylethanal B C6H5CH₂CH₂OHC₂H₂CH₂CO₂H phenylethanol Suggest reagents (shown as A and B in the scheme above) that could be used to carry out the oxidation of the alcohol to the aldehyde and the acid, respectively. C6H5CH₂- Suggest two other syntheses of phenylethanoic acid, in each case indicating the starting materials and other reagents required, but not giving details of mechanism. One of your proposed syntheses must start with a compound which only contains seven carbon atoms (the acid product contains eight carbon atoms). phenylethanoic acid Phenylethanal can be converted to a hydrate in the presence of aqueous acid, though the position of equilibrium is very far to the left: H H+/H₂O OH C6H5CH₂-C-H OH Explain why…
