The invention relates to thiazole derivatives corresponding to the general formula: ##STR1## in which: R.sub.1 and R.sub.2 each independently represent hydrogen; a C.sub.1 -C.sub.4 alkyl group; a phenyl group or a phenyl group monosubstituted or polysubstituted by a halogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.1 -C.sub.4 alkoxy, nitro or hydroxyl group; or one of the groups R.sub.1 and R.sub.2 denotes hydrogen and the other represents a naphthyl group; a benzyl group; an .alpha.,.alpha.-dimethyl-benzyl group; a cyclohexyl group; a biphenyl group; a thienyl group of an adamantyl group; or alternatively R.sub.1 and R.sub.2, taken together, represent a group; ##STR2## in which the phenyl group is bonded to the 4-position of the thiazole and the group (CH.sub.2).sub.m to the 5-position, m represents an integer equal to 2 or 3 and R.sub.5 denotes hydrogen or a nitro group, R.sub.3 is H or an alkyl group and R.sub.4 is notably an alkyl substituted by an amino group, a pyrrolidino, or a pyridino group.
该发明涉及与通式对应的噻唑衍生物:##STR1##其中:R.sub.1和R.sub.2各自独立地代表氢;一个C.sub.1-C.sub.4烷基基团;一个苯基或一个被卤原子、C.sub.1-C.sub.4烷基、C.sub.1-C.sub.4烷氧基、硝基或羟基单取代或多取代的苯基;或者R.sub.1和R.sub.2中的一个表示氢,另一个代表萘基;苯甲基;α,α-二甲基苯基;环己基;联苯基;噻吩基或脱氢环戊基;或者R.sub.1和R.sub.2,一起表示一个基团;##STR2##其中苯基与噻唑的4位键合,基团(CH.sub.2).sub.m与5位键合,m表示一个等于2或3的整数,R.sub.5表示氢或硝基,R.sub.3为H或烷基,R.sub.4主要为被氨基、吡咯啉基或吡啶基取代的烷基。
