Acyclic Polyfunctional Molecules

1 ACYCLIC POLYFUNCTIONAL MOLECULES Methyl (35,45 )-4-hydroxy-3-(phenylmethoxy)hex-5-enoate 

The space after methyl and the ate ending tells you this is a methyl ester. The acid from which the ester derives is a six-carbon chain with a double bond between carbons 5 and 6. There is an alcohol function on carbon 4. There is a methoxy group on carbon 3 and a phenyl group on the carbon of the methoxy group. Carbons 3 and 4 are stereogenic atoms each with S configuration as designated. 

This is an example of a derivative name, that is, the first word is the complete name of an alcohol and the other two words describe a derivati-zation where the alcohol is converted to an ether (ketal). Such a name would be useful in discussing a compound that has the ketal present as a temporary entity, for example, as a protecting group.
