摘要:研究了wo 3 /al 2 O 3催化剂上的气相甘油脱水.γ-Al 2 O 3上wo 3 的负载量显着影响丙烯醛的收率,并且wo 3负载量为20Wt%的催化剂表现出最高的活性.Wo 3负载量为20Wt%的wo 3 /al 2 O 3催化剂比其他负载型wo 3催化剂和沸石表现出更高的活性和耐久性.反应后wo 3 /al 2 O 3催化剂的布朗斯台德酸位和介孔数量没有减少,表明甘油不断进入wo 3 /al 2 O 3介孔内的布朗斯台德酸位,从而维持丙烯醛的形成率高.O 2流下的脱水进一步提高了wo 3 /al 2 O 3催化剂的耐久性,从而能够可持续形成丙烯醛.此外,负载量为20Wt%wo 3 的wo 3 /al 2 O 3催化剂对各种多元醇的脱水表现出高活性,能够以高产率提供相应的产物.

摘要:The present invention relates to a novel synthesis method for acyl-pantetheine derivatives. The present invention further relates to the use of said synthesized acyl-pantetheine derivatives as a starting material in the enzymatic synthesis of acyl-coenzyme A derivatives. According to a first aspect thereof, the present invention provides a method for the synthesis of acyl-pantetheine derivatives, the method including the steps of: a) providing a source of pantetheine; b) providing a source of acyl ester; and c) contacting the source of pantetheine with the source of acyl ester to form the corresponding acyl-pantetheine derivative, having the general formula (I), wherein R is an acyl group.The present invention also provides a method for the synthesis of acyl-coenzyme A derivatives as well as the use of a source of pantetheine and a source of acyl ester in the preparation steps of these two methods.

摘要:Methods for the synthesis of cyclic peptides are provided, as well as novel dipeptide compounds. The methods include the solid phase synthesis of a dipeptide, which is the coupled to a second peptide in a solid phase reaction. The peptide is then cyclized following the coupling reaction. The methods and dipeptides are particularly useful for the synthesis of MC-4 receptor agonist peptides.

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.
