Ethers whose organic moieties have asymmetric atoms, methods for their preparation and their use for the resolution of alcohols, phenols or certain compounds with a lactone structure

Abstract: New ethers whose organic residues contain chiral atoms, their process of preparation and their application to the resolution of alcohols, phenols or certain compounds of lactonic structure. The invention relates to new compounds of formula I: in which A is a 1 to 10-membered hydrocarbon chain, which may contain one or more heteroatoms, one or more unsaturations and which may be of the mono or polycyclic type, including spiro or endo, comprising one or more chiral atoms or of spatial configuration causing a chirality, Z is a residue of alcohol or of phenol comprising at least one asymmetric carbon, or of spatial configuration causing a chirality, Z being however different from (R) or (S) α-cyano 3-phenoxy benzyl when A is an chain their process of preparation and their application to the resolution of alcohols, phenols or certain lactones.

Phospholipids as vectors for active molecules, their preparation and their use in cosmetic or dermatologic compositions

Abstract: The subject of the invention is active phospholipids of formula (I): in which: R1 represents in particular an aliphatic chain containing 14 to 24 carbon atoms which is saturated or with 1 or 2 unsaturations, R3 represents in particular a choline, ethanolamine, glycerol, serine, inositol, ethanol, n-propanol, n-butanol or alternatively ethylene glycol residue, and Y is such that represents an active molecule in the 2-position of the glycerol, which is intended to be released under the effect of phospholipases.
