摘要:将杂原子安装到 C−h 键中的化学转化引起了人们的极大兴趣,因为它们简化了增值小分子的构建.直接 C−h 氧基官能化,或将 C−h 键一步转化为 C−o 键,可能是一种高度可行的转化,因为所得的对映体丰富的醇在药物和天然产物中普遍存在.在这里,我们报道了一种用于直接 C−h 羟基化的单烧瓶光氧化还原/酶促过程,该过程具有广泛的反应活性,化学选择性和对映选择性.这种统一的策略促进了一般光氧化还原和酶催化的协同作用,并使化学酶过程能够实现强大的选择性氧化转化.

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:Poly N-substituted Glycines (poly NSGs), wherein the substituents bear purine or pyrimidine bases (R<9>) every second glycine: In addition, a solid phase method for the synthesis of N-substituted oligomers of more general structures is disclosed.The poly NSGs obtainable by this method 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.

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.
