Abstract
Novel ethers of organic compounds containing chiral atoms of the formula ##STR1## wherein A is a hydrocarbonated chain of 1 to 10 groups, the said chain containing one or more heteroatoms, one or more unsaturations, the assembly of the groups constituting the chain may represent a mono- or polycyclic system, including a system of the spiro or endo type, the chain A can contain one or more chiral atoms or the lactone moiety can present a chirality due to the dissymetric spatial configuration of the whole of the molecule and Z is selected from the group consisting of primary, secondary or tertiary alcohol moiety containing at least an asymetric carbon atom, a phenol moiety substituted comprising at least one asymetric carbon atom and an substituted alcohol or phenol moiety with a chirality due to the dissymetric spatial configuration of the whole of the molecule, with the proviso Z is not (R) or (S) .alpha.-cyano-3-phenoxy-benzyl when A is ##STR2## which are useful for the resolution of compounds of the formulae ##STR3## wherein A and Z have the above definitions and X is selected from the group consisting of hydrogen and alkyl of 1 to 4 carbon atoms.
