Synthesis of hydroxytyrosyl alkyl ethers from olive oil waste waters.
The preparation of a new type of derivatives of the naturally occurring antioxidant hydroxytyrosol is reported. Hydroxytyrosyl alkyl ethers were obtained in high yield by a three-step procedure starting from hydroxytyrosol isolated from olive oil waste waters. Preliminary results obtained by the Rancimat method have shown that these derivatives retain the high protective capacity of free hydrox...
متن کاملSolvent-Free Synthesis of Glycidyl Ethers Investigating Factors Influencing the Yield of Alkyl Glycidyl Ethers
Surfactants are a widely used group of chemicals. With a range of applications from soaps to paints and from hygiene products to asphalt they are one of the most diverse product groups available. AkzoNobel in Stenungsund uses glycidyl ethers as intermediates in the productions of some of their surfactants. These glycidyl ethers are produced with some hazardous compounds, which make the handling...
متن کاملA mild and efficient procedure for the synthesis of ethers from various alkyl halides
A simple, mild and practical procedure has been developed for the synthesis of symmetrical and unsymmetrical ethers by using DMSO, TBAI in the presence of K2CO3. We extended the utility of Potassium carbonate as an efficient base for the preparation of ethers. A wide range of alkyl aryl and dialkyl ethers are synthesized from treatment of aliphatic alcohols and phenols with various alkyl hali...
متن کاملAcyl dihydroxyacetone phosphate: precursor of alkyl ethers.
1-0-Alkyl dihydroxyacetone phosphate is biosynthesised in guinea pig liver mitochondria and in rat brain microsomes by direct reaction of a long chain alcohol and acyl dihydroxyacetone phosphate. ATP and Mg* are stimulatory but coenzyme A is not necessary for the reaction. 1-0-Alkyl dihydroxyacetone phosphate (alkyl DHAP)l was shown to be biosynthesized from long chain alcohol and DHAP with ATP...
متن کاملLabeled S-alkyl Glycerol Ethers and Derivatives
P, adioactive S-alkyl glycerol ethers have been synlhesized with 3SS, 14C and 3tt labels as well as 311/35S double labels. Tile synthesized compounds were converted to various derivatives which can serve to characterize tile S-alkyl glycerol ethers. These included tile isopropylidene derivative, oxidation with periodate to the aldehyde followed by reduction with LiAIH4 to tile alcohol, and reac...
