ABSTRACT:
A process for the resolution of hemiacetal compounds of the formula ##STR1## wherein A is a hydrocarbon chain containing 1 to 16 groups, the said chain optionally containing at least one heteroatom, at least one unsaturation, the assembly of the group constituting the chain may be a mono- or polycyclic system including a spiro or endosystem and the assembly of chain A and the carbon atoms attached thereto can contain at least one chiral atom or the hemiacetal moiety thereto which can present a chirality due to the dissymetric spatial configuration of the molecule and Y is selected from the group consisting of hydrogen, alkyl of 1 to 18 carbon atoms optionally substituted, --CY.sub.3 ' and the .beta.,.gamma.bond together with Y can be part of A and Y' is bromine or chlorine and the resolution of alcohols of the formula
