标题:甲基正丙基醚与oh,No 3和cl的气相反应:动力学和机理
摘要:甲基正丙基醚(mnpe),Ch 3 och 2 Ch 2 Ch 3与oh和no 3自由基以及cl原子的反应在室温(293+/-2 K)和大气压下的速率常数已经确定. 100 L Fep-Teflon反应室与气相色谱-火焰电离检测器(gc-Fid)结合作为检测技术.将所得到的速率常数ķ(以cm为单位3分子-1小号-1)为(9.91+/-2.30)x10-12,(1.67+/-0.32)x10-15,和(2.52+/-0.14)x10-10为与oh,No反应分别为3和cl.通过气相色谱-质谱法(gc-Ms)研究了这些反应的产物,并提出了观测到的反应产物的形成机理.根据不同反应的速率常数计算得出的醚的大气寿命表明,Mnpe的主要损失过程是其与oh的反应,而在沿海地区和海洋边界层中,Cl反应引起的mnpe损失也很重要.

摘要:An object of the present invention is to provide a method for synthesis of keto acids by hydration of an acetylene compound (acetylene-carboxylic acids) under mild conditions free from harmful mercury catalysts and a method for synthesis of amino acids from acetylene-carboxylic acids in a single container (one-pot or tandem synthesis). In one embodiment of the method according to the present invention for synthesis of keto acids, acetylene-carboxylic acids is hydrated in the presence of a metal salt represented by General Formula (1), n nwhere M 1 represents an element in Group VIII, IX, or X of the periodic table, and X 1 , X 2 , or X 3 ligand represents halogen, H 2 O, or a solvent molecule, and k represents a valence of a cation species, and Y represents an anion species, and L represents a valence of the anion species, and each of K and L independently represents 1 or 2, and k×m=L×n.

标 题 :Intermediates in the synthesis of prostaglandins
发明人：TAUB DAVID; WENDLER NORMAN L
权利人:MERCK & CO INC
摘要:The invention relates to a new and novel synthesis of prostaglandin E 2 , and it particularly relates to a novel process starting with relatively inexpensive starting materials. The invention further relates to a synthesis which is readily adaptable for large scale processing because of the high yields in the individual reaction steps. n The invention further relates to novel compounds formed as intermediates in the synthesis of prostaglandin E 2 . The invention still further relates to synthetic analogs and known metabolites of prostaglandin E 2 and prostaglandin E 1 , useful as standards in certain biological assays for determining prostaglandin-like activity.

摘要:A solid phase synthetic method for making substituted 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one. The method is useful for synthesis of large numbers of compounds through automated parallel synthesis or combinatorial library generation and is thus important to rapid discovery or new therapeutic agents containing the base structure of 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one.
