Provide a molecular structure that corresponds to the given name.
(e) (R)-N,N-diethyl 5-cyclohexyl-3-methoxypentanamide

검증된 단계별 안내
1
Identify the main functional group in the compound name, which is 'pentanamide'. This indicates the presence of a five-carbon chain with an amide group (\( \text{CONH}_2 \)).
Determine the substituents on the main chain. The name specifies '3-methoxy', meaning a methoxy group (\( \text{OCH}_3 \)) is attached to the third carbon of the pentanamide chain.
Locate the '5-cyclohexyl' group, which indicates a cyclohexyl group (a six-carbon ring) is attached to the fifth carbon of the pentanamide chain.
Consider the 'N,N-diethyl' prefix, which means two ethyl groups (\( \text{C}_2\text{H}_5 \)) are attached to the nitrogen atom of the amide group.
Ensure the stereochemistry is correct by assigning the (R) configuration at the chiral center. This involves prioritizing the groups attached to the chiral center according to the Cahn-Ingold-Prelog rules and arranging them to determine the (R) configuration.
