Synthesis of aminoderivatives of 4,5,6,7-tetrahydro-benzothiazole. I. 4,5,6- and 7-amino and N-methyl amino derivatives with central dopaminergic activity

4-Oxo and 6-oxo-4,5,6,7-tetrahydro-benzothiazoles were prepared from diester derivatives of thiazole through Dieckmann cyclisation. The 7-oxo compound was synthesized by formation of a thiazole ring on 2-bromo-1,3-cyclohexanedione. The ketones were tranformed into amines and N-methylamines by reductive amination. The 5-amino derivatives were obtained by Hofmann reaction of the corresponding amides. The amines and N-methylamines in the 6-position have central dopaminergic properties. Their isomers in the 4, 5 or 7 positions are inactive.

Synthesis of aminoiderivatives of 4,5,6,7-tetrahydro-benzothiazole. II. 4, 5 and 6-aminomethyl derivatives with cardiovascular activity

The ethyl esters of 4,5,6,7-tetrahdyro-benzothiazolyl-4 carboxylic acids were synthesized from corresponding ethyl 1-oxo-2 bromo-cyclohexane-carboxylates. Their reduction to alcohols, which were then transformed into tosylates, leads to the aminomethyl derivatives. These derivatives are practically devoid of antihistaminic H2 and dopaminergic activities but have interesting cardiovascular properties.
