3,4-DIHYDROISOQUINOLINE Chemical Properties,Usage,Production

Uses

3,4-Dihydroisoquinoline is derived from 1,2,3,4-Tetrahydroisoquinoline (T293820), which is used as a reagent in the preparation of 4-(1,2,4-oxadiazol-5-yl)piperidine-1-carboxamides as antiproliferative tubulin inhibitors.

Uses

3,4-Dihydroisoquinoline can be used as a reactant to synthesize:

5,6-Dihydro-8H-isoquino[1,2-b]quinazolin-8-one by decarboxylative cyclization reaction with isatoic anhydride using tetrabutylammonium iodide (TBAI).
1-naphtholyl tetrahydroisoquinoline by aza-Friedel-Crafts reaction with various naphthols.
3,4-dihydroisoquinoline pseudo bases, which are employed as starting materials for the preperation of 3-benzazepine derivatives.
