Condensations of chiral diamines 11a-c with benzotriazole and formaldehyde gave benzotriazolyl intermediates 12a-c; similar condensations of alpha-amino-amides 10a-c with benzotriazole and paraformaldehyde gave 14a-c. Subsequent treatment of 12a-c and 14a-c with AlCl(3) led to enantiopure tricyclic 1,2,3,5,10,10a-hexahydroimidazo[1,5-b]isoquinolines 1a-c and 2,3,10,10a-tetrahydroimidazo[1,5-b]isoquinolin-1(5H)-ones

We have investigated the effects of mono-substitutions with the conformationally restricted amino acid, 1,2,3,4 tetrahydroisoquinoline-3-carboxylic acid (Tic) at position 3 in arginine vasopressin (AVP), at positions 2, 3 and 7 in potent non-selective cyclic AVP V2/V1a antagonists, in potent and

A molecular mechanics study (grid search and energy minimization) of the highly delta receptor-selective delta opioid antagonist H-Tyr-Tic-Phe-OH (TIP; Tic: tetrahydroisoquinoline-3-carboxylic acid) resulted in four low energy conformers with energies within 2 kcal/mol of that of the lowest energy structure.

Tic, short for 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, is a kind of unnatural α-amino acids. Due to its distinct geometrical conformation and biological activity, the structure of Tic, regarded as the surrogate of proline and the rigid analogue of phenylalanine or tyrosine, has
