摘要:钯 (II) 催化的介观构型双环 [2.2.1] 烯烃支架的氢化硅烷化被证明是开发基于硅立体硅烷作为立体诱导剂的试剂控制的不对称转化的宝贵模型反应.在本研究中,揭示了降冰片烯型基材的对映异构区分单氢化硅烷化中硅烷取代模式的微妙结构要求.将此化学扩展到降冰片二烯的双氢化硅烷化需要立体化学复杂性的显着增加.尽管在第一次氢化硅烷化中需要通过手性试剂区分对映位置,但在第二次中必须使用相同的试剂区分非对映位置.在这种双氢化硅烷化中发现了显着的高立体控制,其中几种硅烷首先用于降冰片烯型系统的氢化硅烷化.根据硅烷的对映体纯度,分别获得 C2-和 Cs-对称加合物.通过结晶分析揭示了关键季硅烷的身份.通过这种方法,还分配了相对和绝对构型,这反过来意味着硅上的所有对映特异性取代都以立体保留进行.在这些固态结构的基础上,我们还讨论了硅烷取代对钯 (II) 催化的氢化硅烷化反应的非对映选择性决定步骤的结构影响.(©

摘要:A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two 'sub-monomers' directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a solid support-bound alpha -haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability. Combinatorial libraries of cyclic compounds are disclosed wherein the cyclic compounds are comprised of at least one ring structure derived from cyclization of a peptoid backbone. The diversity of product compounds is generated by the sequential addition of substituted submonomers. The combinatorial library includes 10 or more, preferably 100 or more, and more preferably 1,000 or more distinct and different compounds. The library includes each of the product compounds in retrievable and analyzable amounts and preferably includes at least one biologically active compound. Methods of synthesizing the combinatorial libraries and assay devices produced using the libraries are disclosed as is methodology for screening for and obtaining biologically active cyclic organic compounds.

标 题 :Sulfoxide ligand metal catalyzed oxidation of olefins

摘要:The enantioselective synthesis of isochroman motifs has been accomplished via Pd(II)-catalyzed allylic C—H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide-oxazoline (ArSOX) ligand. The allylic C—H oxidation reaction proceeds with the broadest scope and highest levels asymmetric induction reported to date (avg. 92% ee, 13 examples ≥90% ee). Additionally, C(sp 3 )-N fragment coupling reaction between abundant terminal olefins and N-triflyl protected aliphatic and aromatic amines via Pd(II)/sulfoxide (SOX) catalyzed intermolecular allylic C—H amination is disclosed. A range of 52 allylic amines are furnished in good yields (avg. 76%) and excellent regio- and stereoselectivity (avg. >20:1 linear:branched, >20:1 E:Z). For the first time, a variety of singly activated aromatic and aliphatic nitrogen nucleophiles, including ones with stereochemical elements, can be used in fragment coupling stiochiometries for intermolecular C—H amination reactions.

标 题:Process for the synthesis of o-substituted oxime compounds
发明人：CHEMPOLIL THOMAS MATHEW
权利人:ALLIED SIGNAL INC
摘要:A novel process for the production of O-substituted oximes is disclosed. The process involves reacting an oxime with an alkali-metal hydroxide optionally in a solvent which forms an azeotrope with water to form a mixture of the alkali metal salt of the oxime and water, removing all or a portion of the water by distilling the mixture azeotropically and reacting the distilled mixture with an alpha halo carboxylic acid.
