一种五元环酮，羰基碳两侧的环路径等价。

化学式
C5H8O
官能团
酮
摩尔质量

Also known as
Adipic ketone, Ketocyclopentane, Ketopentamethylene, Dumasin, Adipinketon, Adipin keton

概览

Reduction produces cyclopentanol. In this unsubstituted ring, the two directions around the ring are equivalent, so the alcohol-bearing carbon is not a stereogenic centre. Ring substitution can remove that equivalence and change the stereochemical outcome.
