Nomenclature 3-keto esters

Although a polyfunctional organic molecule might contain several different functional groups, we must choose just one suffix for nomenclature purposes. It s not correct to use two suffixes. Thus, keto ester 1 must be named either as a ketone with an -one suffix or as an ester with an -oate suffix but can t be named as an -onoate. Similarly, amino alcohol 2 must be named either as an alcohol (-0/) or as an amine (-amine) but can t be named as an -olamine or -anritiol.

Hyphens, on the other hand, are used less in USA than in British practice (see p. 38). Identical letters belonging to different words are not separated by hyphens in USA (methyllithium, tetraacetate) hyphens are not used in words such as coordinate, unionized, nor to join portions/ of partial names (keto ester, amino acid), nor after voiced vowels ending isolated parts of nomenclature (thia compound, methoxy group, amino derivative). They are also not used between a multiplicative prefix and a parenthesis, e.g.j in USA it is correct to write p-bis(2 -chloroethyl)-benzene in Great Britain the name would start p-di-(2-... or p-bis-(2-... on the grounds that parentheses do not alter pre-existing punctuation.
