Parent Hydrides

R-2.4.6 Natural product parent hydrides

Many naturally occurring compounds belong to well-defined structural classes, each of which can be characterized by a set of cognate parent structures that are closely related structurally. In naming natural product structures, the main objective is to choose a parent structure that includes as much as possible of the configurational detail common to the relevant class of natural products; such a parent structure has become known as a stereoparent. A numbering pattern established among a group of structurally related natural products is normally used for numbering the skeletal atoms of the stereoparent. Nomenclature for natural products is described briefly in Section F of the 1979 edition of the IUPAC Nomenclature of Organic Chemistry.
