KAWTHEKAR, Rahul B. et al. Synthesis of (S)-3-aminoethyl-1,2,3,4-tetrahydroisoquinoline (TIQ-diamine) via the Mitsunobu protocol. S.Afr.j.chem. (Online) [online]. 2010, vol.63, pp.195-198. ISSN 1996-840X.
The synthesis of (S)-3-Aminoethyl-1,2,3,4-tetrahydroisoquinoline (TIQ-diamine) was successfully achieved via the Mitsunobu protocol. The method from earlier reports utilizing aminolysis of commercially available TIQ-amino methyl ester, and reduction of the amide, proved to be inadequate for preparation of TIQ-diamines. The modified route requires three additional steps and consequently rendered three novel intermediates, which were furnished under mild conditions.
