Compounds of formula (I): ##STR1## (in which: R.sup.1 is hydrogen or alkl; R.sup.2 is a variety of groups or atoms; R.sup.3 is optionally substituted hydroxy or --(NH).sub.n --NR.sup.5 R.sup.6, wherein R.sup.5 and R.sup.6 are a variety of groups or atoms, preferably alkyl substituted by heterocyclic, and n is 0 or 1; Q is oxygen or sulfur; and A is a C.sub.1 -C.sub.6 alkylene group) have valuable cardiotionic activity and may be used for the treatment of cardiac disorders. They may be prepared from corresponding compounds containing a benzene ring with a group --QH at the 1-position and a group --CO--CHR.sup.1 --NH--COOR.sup.7 at the 4-position by ring closure and introduction of the group of formula --A--CO--R.sup.3 in any order.
式(I)的化合物:##STR1##(其中:R.sup.1为氢或烷基;R.sup.2是各种基团或原子;R.sup.3是可选择地取代的羟基或--(NH).sub.n --NR.sup.5 R.sup.6,其中R.sup.5和R.sup.6是各种基团或原子,最好是被杂环基取代的烷基,n为0或1;Q为氧或硫;A为C.sub.1 -C.sub.6烷基基团)具有有价值的心脏强心活性,可用于治疗心脏疾病。它们可以通过环闭合和引入式--A--CO--R.sup.3的基团来制备,这些基团可以以任何顺序从含有苯环的化合物中得到,其中该化合物在1-位置带有--QH基团,4-位置带有--CO--CHR.sup.1 --NH--COOR.sup.7基团。
