标题 :Synthesis of N-substituted oligomers

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 resin-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.

摘要:The present invention provided a continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts. Diazotization, reduction, acidic hydrolysis and salifying with acids are innovatively integrated together. Using acidic liquids of aniline or substituted aniline, diazotization reagents, reductants and acids as raw materials, phenylhydrazine derivative salts is obtained through the synthesis process, which is a three-step continuous tandem reaction including diazotization, reduction, acidic hydrolysis and salifying. The described synthesis process is a kind of integrated solutions, which is carried out in an integrated reactor. The feed inlets of the integrated reactor are continuously filled with raw materials. In the integrated reactor, diazotization, reduction, acidic hydrolysis and salifying are carried out continuously and orderly, and phenylhydrazine salts or substituted phenylhydrazine salts is obtained in the outlet of the integrated reactor without interruption. The total reaction time is no more than 20 min.

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.
