Diheterocyclic esters of 4-(1,1-bis-(phenoxy-propionic or -butoyric acid)-cyclohexane){60 -methyl substituted

摘要

Bisphenoxy carboxylic acid derivatives useful as an antiarteriosclerosis agent with good absorbability and low toxicity, which are novel compounds represented by the general formula, <IMAGE> (I) wherein R1 and R2 represent hydrogen atoms or lower alkyl groups and A preresents <IMAGE> (wherein in case R3 is a hydrogen atom, R4 represents an amino-lower-alkyl group, an N-lower-alkylaminoalkyl group, a heterocyclic group, or a heterocyclic group-substituted alkyl group; or R3 and R4 may join through an intermediary hetero atom to form a heterocyclic group and if said hetero atom is a nitrogen atom, this nitrogen atom can bear a lower alkyl group as a substituent) or <IMAGE> (wherein R5 represents a hydrogen atom, a hydroxyalkyl group or a derivative thereof, and R6 represents a hydroxyalkyl group or a heterocyclic group; or R5 and R6 may join to form a cyclic group, or may join through another intermediary hetero atom to form a heterocyclic group and if said hetero atom is a nitrogen atom, this nitrogen atom can bear a lower alkyl group as a substituent).
