NOVEL ETHERS WITH ORGANIC REMAINS CONTAINING CHIRAL ATOMS, THEIR PREPARATION PROCESS AND THEIR APPLICATION TO THE SPLITTING OF ALCOHOLS OR CERTAIN HEMIACETAL STRUCTURE COMPOUNDS.

摘要

Compounds of the formula IMAGE III wherein A is a hydrocarbon chain containing 1 to 16 groups, the said chain 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, -CY3' and the beta , gamma bond together with Y can be part of A and Y' is bromine or chlorine.
