Abstract
Derivatives of benzocycloalkenyldihydroxyalkanoic acids, inhibitors of HMG CoA reductase, antagonists of thromoboxane A.sub.2 receptors and antifungals, denoted by the formula I ##STR1## in which X=CH.sub.2, O or S; R.sub.1 and R.sub.2, identical or different, =H, C.sub.1-3 alkyl or together from a --(CH.sub.2).sub.n -- chain (n=4,5) optionally substituted symmetrically by one or two C.sub.1-3 alkyl radicals. R.sub.3 and R.sub.4, identical or different, =H, CF.sub.3, halogen (Cl, F, Br), C.sub.1-5 N,N-dialkylamino, C.sub.1-4 alkyl, C.sub.1-5 -alkoxy, C.sub.1-3 alkylthio, or phenyl optionally substituted by at most two substitutents which may be identical or different and may denote C.sub.1-3 alkyl or C.sub.1-3 alkoxy radicals or halogens (F, Cl), it being understood that when one of R.sub.3 and R.sub.4 denotes the radicals: CF.sub.3, N,N-dialkylamino, C.sub.6 H.sub.5 or substituted phenyl, it is present at the vertices 3', 4'or 5' according to formula 1 and the other denotes a hydrogen atom. R.sub.5 and R.sub.6, (which may be identical or different)=H, halogen (F, Cl, Br), CF.sub.3, C.sub.1-3 alkyl, C.sub.1-3 alkoxy, C.sub.6 H.sub.5, optionally substituted by at most two substitute…
