The invention provides novel thiomorpholines of the formula (I) ##STR1## and their pharmaceutically acceptable acid addition salts wherein n represents 0 or 1, R.sup.1 represents (lower)alkyl, R.sup.2 represents hydrogen or (lower)alkyl, R.sup.3 represents hydrogen, lower alkyl, lower alkenyl, lower alkynyl, aryl(lower)alkyl, 2-tetrahydrofurylmethyl or cycloalkylmethyl and R.sup.4 represents hydrogen, hydroxy, acyloxy or a protected hydroxy group, with the proviso that when n is 0, R.sup.4 is other than hydrogen. The compounds in which n is 0 and R.sup.4 is lower alkoxy, hydroxy or acyloxy are analgesics and/or opiate antagonists and the compounds in which n is 1 and R.sup.4 is hydrogen are hypotensives or anti-hypertensives. The other compounds of formula (I) are intermediates for the pharmacologically active compounds.
该发明提供了公式(I)中的新型硫代吗啉及其药学上可接受的酸盐,其中n代表0或1,R.sup.1代表(较低)烷基,R.sup.2代表氢或(较低)烷基,R.sup.3代表氢、较低烷基、较低烯基、较低炔基、芳基(较低)烷基、2-四氢呋喃甲基或环烷基甲基,R.sup.4代表氢、羟基、酰氧基或保护羟基,但当n为0时,R.sup.4不是氢。其中,n为0且R.sup.4为较低烷氧基、羟基或酰氧基的化合物是镇痛剂和/或阿片拮抗剂,而n为1且R.sup.4为氢的化合物是降压剂或抗高血压剂。公式(I)中的其他化合物是药理活性化合物的中间体。
