摘要:A method for the synthesis of cyclic acetals comprises reacting at least one carbonyl-function compound selected from aldehydes, ketones, and/or linear acetals, on a polyol in a concentrated aqueous solution exceeding 20 wt % in a reactor containing an acidic catalyst. The carbonyl-function compound is selected so that the cyclic acetal obtained has a water solubility lower than 20000 mg/kg. During the catalytic reaction for the cyclic acetal synthesis, at least one portion of the organic phase containing the cyclic acetal is separated. The acidic catalysis is either homogeneous when using a water-soluble strong acid, or heterogeneous when using a solid acid such as a resin, a zeolite, or any appropriately acidified solid. The extractive reaction method can be used for obtaining high conversions and selectivity.

权利人:ATLANTIC RICHFIELD CO
摘要:A process for the preparation of oxalate esters by the catalytic oxidative carbonylation of acetals and ketals with carbon monoxide and oxygen-containing gas in the presence of a metal salt catalyst, an amine base and a catalytic amount of an alcohol. Preferably a catalytic amount of particular metal oxidizing salts is employed along with a catalytic amount of an acid or an amine salt compound. Alternatively various counterions and ligands of the metal salt catalysts may be employed.

摘要:PCT No. PCT/JP83/00263 Sec. 371 Date Apr. 4, 1984 Sec. 102(e) Date Apr. 4, 1984 PCT Filed Aug. 12, 1983 PCT Pub. No. WO84/00755 PCT Pub. Date Mar. 1, 1984.This invention provides novel aminopolyol derivative represented by the general formula (I) wherein each of R and R' represents a hydrogen atom, or an alkyl or aryl group or R and R', taken together, form an alkylene group, R1 represents a lower alkyl group, R2 represents a hydrogen atom or an acyl group, and R3 represents a lower alkyl group; and a process for production thereof. The aminopolyol derivatives of formula (I) are useful as intermediates for the synthesis of amino sugars such as 3-epi.daunosamine, acosamine, ristosamine and daunosamine which is the sugar moiety of daunomycin useful as an anti-cancer agent.

摘要:The invention relates to a method for producing an intermediate product containing a heterocyclic quarternary ammonium and/or guanidium cation, for the synthesis of heterocyclic quaternary ammonium and/or guanidium compounds. According to said method, heterocyclic quaternary ammonium and/or guanidium carboxylates are oxidised with an oxidising agent in the presence of a metal from groups 8 to 10 of the periodical table, at a temperature of between 0 and 250 °C and a pressure of between 0.05 and 20 MPa abs.
