Compounds in the Advanced Asymmetrics catalog have been named to keep analogs as close together in the catalog as possible. In addition, derivatives are alphabetized to keep them near their parent chiral compounds so they will be found easily. Please remember the following when searching for a compound:

• Compounds such as esters, amides, etc. are named so that the side containing the chiral center comes first. For example, the catalog would contain the name "(S)-Lactic acid, methyl ester", but "(−)-Menthyl acetate". If both sides contain chiral centers, the molecule is named with the chiral centers most important to its use in synthesis coming first, as in (S)-toluenesulfinic acid, (1R,2S,5R)-menthyl ester.
• Protected and activated chiral compounds occur in the catalog just after their parent molecule. For example, "L-Phenylalanine", "N-Acetyl-L-phenylalanine", "FMOC-L-Phenylalanine", and "L-Phenylalanine, NHS ester" are all listed in the "P"s in the catalog.
• Substituted amino acids are indexed normally. For example, the names, "p-Nitro-L-phenylalanine", "N-^tBOC-p-Nitro-L-phenylalanine", and "p-Nitro-L-phenylalanine, methyl ester" are all listed in the "N"s in the catalog.
• In confusing cases, or if you wish to see all available derivatives of a class of compound, you can browse by functional group.
• N- and O-substituted amino acids and amino alcohols are indexed first according to their N-substituent (with the unsubstituted compound coming first), then according to their O- substituent (with the unsubstituted compound coming first). For example, "Alanine", "Alanine, methyl ester", "BOC-Alanine", "BOC-Alanine, methyl ester", and "FMOC-Alanine" are listed in that order.
• D- isomers are listed before L- isomers. R isomers are listed before S isomers. Dextrorotatory isomers are listed before levorotatory isomers.
