Decahydroisoquinoline is a nitrogen-containing heterocycle with the chemical formula C
9H
17N.[1] It is the saturated form of isoquinoline.
Decahydroisoquinoline can be formed by the hydrogenation of isoquinoline or tetrahydroisoquinoline.[2]
Isomers[]
There are four stereoisomers of decahydroisoquinoline which differ by the configuration of the two carbon atoms at the ring fusion:
(4aR,8aR)‐cis-decahydroisoquinoline
(4aS,8aS)‐cis-decahydroisoquinoline
(4aR,8aS)‐trans-decahydroisoquinoline
(4aS,8aR)‐trans-decahydroisoquinoline
Occurrence[]
The decahydroisoquinoline occurs naturally in some alkaloids, including gephyrotoxins and which are found in amphibian skins.[3]
A variety of pharmaceutical drugs include a decahydroisoquinoline ring system within their structure, including ciprefadol,[4] dasolampanel,[5] nelfinavir,[6] saquinavir,[7] and tezampanel.[8]
