Alkaloids means . NOMENCLATURE & RING SYNTHESIS. NOMENCLATURE OF HETEROCYCLIC COMPOUNDS. DEFINITION:. A cyclic organic compound containing all carbon atoms in ring formation is referred to as a carbocyclic compound.. Chapter 16. Amines. Amines are nitrogen-containing compounds. Structure and Classification. Amines are classified as 1°, 2°, or 3° depending on the number of carbon groups bonded to nitrogen.. Aliphatic amine:. Dr. Sheppard, CHEM 4201, Fall 2014.

Alkaloids are a group of naturally occurring chemical compounds that mostly contain nitrogen atom in the heterocycles and originate from amino acids. This group also includes some related compounds with neutral, and even weakly acidic properties. . Dr. . R. . P. Patil. Professor & Head. Department of . Botany. Deogiri . College, Aurangabad.
