Acyl 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 کاملOxidation of Secondary Methyl Ethers to Ketones
We present a mild way of converting secondary methyl ethers into ketones using calcium hypochlorite in aqueous acetonitrile with acetic acid as activator. The reaction is compatible with various oxygen- and nitrogen-containing functional groups and afforded the corresponding ketones in up to 98% yield. The use of this methodology could expand the application of the methyl group as a useful prot...
متن کاملSynthesis of unsymmetrical alkyl acetals via addition of primary alcohols to allyl ethers mediated by ruthenium complexes
ABSTRACT Ru-catalyzed synthesis of mixed alkyl-alkyl acetals via addition of primary alcohols to allyl ethers has been extended to include long-chain and/or functionalized substrates. The catalytic systems for these reactions were generated from RuCl2(PPh3)3 and [RuCl2(1,5-COD)]x and phosphines [PPh3 or P(p-chlorophenyl)3] or SbPh3. Of particular importance is the almost quantitative eliminatio...
متن کاملOxidation of primary alcohols to methyl esters by hydrogen transfer.
The oxidation of alcohols in the presence of methanol has been achieved using a ruthenium catalyst with crotononitrile as the hydrogen acceptor.
متن کاملAlcohols and Ethers
T he hydroxyl group is one of the most important functional groups of naturally occurring organic molecules. All carbohydrates and their derivatives, including nucleic acids, have hydroxyl groups. Some amino acids, most steroids, many terpenes, and plant pigments have hydroxyl groups. These substances serve many diverse purposes for the support and maintenance of life. One extreme example is th...
