Class Information
Number: 548/532
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Hetero ring is five-membered consisting of one nitrogen and four carbons (e.g., halopyrrolidines, etc.) > Having -c(=x)-, wherein x is chalcogen, bonded directly to the five membered hetero ring (e.g., pyrrole carbonyl halides, pyrrole carboxaldehyde, etc.) > The -c(=x)- is part of a -c(=x)x- group, wherein the x's are the same or diverse chalcogens (e.g., pyrrole-3-carboxylic acid, etc.) > And is bonded directly to a ring carbon which is adjacent to the ring nitrogen of the five-membered hetero ring (e.g., 4-hydroxy proline, etc.)
Description: Compounds wherein the X group is bonded directly to a ring carbon of the five-membered hetero ring which is adjacent to the ring nitrogen.
