(S)-4-tert-Butyl-2-(1,2,3,4-tetra-hydro-isoquinolin-3-yl)-1,3-thia-zole.

ABSTRACT: In the title compound, C(16)H(20)N(2)S, a potential tetra-hydro-isoquinoline (TIQ) thia-zole ligand, the N-containing six-membered ring of the TIQ unit adopts a half-chair conformation. There are four mol-ecules in the asymmetric unit. No classical hydrogen bonds or π-π inter-actions were found in the crystal structure.

Ortho-rhom-bic polymorph of (6,7-dimeth-oxy-1,2,3,4-tetra-hydro-isoquinolin-1-yl)methanol.

Project description:The asymmetric unit of the title compound, C(12)H(17)NO(3), contains two mol-ecules with different conformations. It is a polymorph of the monoclinic form [El Antri et al.
