An acid–base reaction of (R)-sec-butylamine with a racemic mixture of 2phenylpropanoic acid forms two products having different melting points and somewhat different solubilities. Draw the structure of these two products. Assign R and S to any stereogenic centers in the products. How are the two products related? Choose from enantiomers, diastereomers, constitutional isomers, or not isomers of each other.
Although ibuprofen is sold as a racemic mixture, only the S enantiomer acts as an analgesic. In the body, however, some of the R enantiomer is converted to the S isomer by tautomerization to an enol and then protonation to regenerate the carbonyl compound. Write a stepwise mechanism for this isomerization.
5-Hydroxyhexanal forms a six-membered cyclic hemiacetal, which predominates at equilibrium in aqueous solution.
(a) Draw a structural formula for this cyclic hemiacetal.
(b) How many stereoisomers are possible for 5-hydroxyhexanal?
(c) How many stereoisomers are possible for this cyclic hemiacetal?
(d) Draw alternative chair conformations for each stereoisomer and label groups axial or Also predict which of the alternative chair conformations for each stereoisomer is more stable.
