This invention relates to new tetrahydrobenzthiazoles of general formula ##STR1## wherein R.sub.1 represents a hydrogen atom, an alkyl group, an alkenyl or alkynylk group, an alkanoyl group, a phenyl alkyl or phenyl alkanoyl group, while the above mentioned phenyl nuclei may each be substituted by 1 or 2 halogen atoms, R.sub.2 represents a hydrogen atom or an alkyl group, R.sub.3 represents a hydrogen atom, an alkyl group a cycloalkyl group, an alkenyl or alkynyl group, an alkanoyl group, a phenyl alkyl or phenyl alkanoyl group, while the phenyl nucleus may be substituted by flurorine, chlorine or bromine atoms, R.sub.4 represents a hydrogen atom, an alkyl group, an alkyl or alkenyl group, or R.sub.3 and R.sub.4 together with the nitrogen atom between them represent a pyrrolidino, piperidino, hexamethyleneimino or morpholino group, the enantiomers and the acid addition salts thereof. The compounds of general formula I above in which one of the groups R.sub.1 or R.sub.3 or both groups R.sub.1 and R.sub.3 represent an acyl group are valuable intermediate products for preparing the other compounds of general formula I which have valuable pharmacological properties. The new compounds may be prepared using methods known per se.
这项发明涉及一种新的四氢苯并噻唑类化合物,其一般化学式为##STR1##其中R.sub.1代表氢原子、烷基、烯基或炔基、醇酰基、苯基烷基或苯基醇酰基,上述提到的苯核可以分别被1或2个卤素原子取代,R.sub.2代表氢原子或烷基,R.sub.3代表氢原子、烷基、环烷基、烯基或炔基、醇酰基、苯基烷基或苯基醇酰基,而苯核可以被氟、氯或溴原子取代,R.sub.4代表氢原子、烷基、烷基或烯基,或者R.sub.3和R.sub.4与它们之间的氮原子一起代表吡咯啉基、哌啶基、己亚甲基胺基或吗啉基,以及其对映体和酸盐。上述一般式I中的化合物中,R.sub.1或R.sub.3中的一个或两个代表酰基的基是制备具有有价值的药理特性的一般式I其它化合物的有价值的中间体。这些新化合物可以使用已知方法制备。
