dorane

Dorane is a term found in historical organic chemistry literature used to describe a class of polycyclic hydrocarbon skeletons. It does not denote a single, well-defined compound in current IUPAC terminology; rather, it has appeared in various sources to refer to a compact, fused-ring framework that resembles a tri-cyclic or cage-like system. The precise topology associated with dorane has never been standardized, and the term is rarely used in modern chemical nomenclature.

In older treatments, dorane was described as a hydrocarbon skeleton formed by three to four fused rings with limited flexibility and notable three-dimensional character. Because descriptions vary between authors, "dorane" functions more as a historical label than a fixed structural descriptor. Modern texts generally prefer explicit structural names that unambiguously specify ring fusion patterns and substituent positions.

As a consequence, there are few, if any, contemporary syntheses or applications named explicitly "dorane." When the term appears in current discussions, it is typically in historical or pedagogical contexts to illustrate concepts in polycyclic hydrocarbon chemistry, ring strain, or nomenclature debates rather than as a reference to a defined, actionable compound.
