Labeled 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...
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 کاملI3C/l2C Isotope Effects in Alkyl Ethers
The ' 3C/1 'C isotope effect, conventionally represented by the reduced isotopic partition function ratio, (S2/S1) f , for a pair of 13C and 12C isotopic molecular species, in a series of alkyl ethers having a transferable molecular force field, has been analysed by a statistical-mechanical perturbation theory approach by expressing it as multiplicative factors: C factors, representing individu...
متن کاملReactions of vinyl ethers with cobalamins and cobaloximes.
Sir: We recently reported 1 that cobaloximes and cobalamins reacted with vinyl ethers, in the presence of alcohols, to give aceta Is containing cobalt-carbon cr-bonds. On the basis of these, and earlier 2 experiments, we suggested that the reactions proceeded via the intermediary of a Co(lII)-olefin 7r-complex. Schrauzer, et al.,3 then reported that they were unable to confirm our results and c...
متن کاملTriphenylphosphine mediated synthesis of functionalized aryl-vinyl ethers from7-hydroxy coumarin and methyl acetylene carboxylate
7-hydroxy coumarin undergoes neutral conditions with alkyl propiolates in the presence of triphenylphosphine, and bysubstituation the corresponding aryl vinyl ethers was obtained in good yields
