摘要:The present invention relates to the synthesis of polycyclic aromatic compounds. Compounds such as terrylene or quaterrylene may now be prepared in relatively high yield by reaction of naphthalene or perylene via Scholl-type coupling in the presence of a superacid and an oxidant in an inert solvent.

摘要:A method for the synthesis of aryl thioglycosides comprising a sialylated residue of β-D-galactose is disclosed. The method consists of preparing by a chemical synthesis a non-sialylated aryl thioglycoside, and enzymatically sialylating the latter with a sialic acid in the presence of a suitable sialyltransferase. The sialylated aryl thioglycoside is then chemically derivatized by standard procedures, to provide a derivative suitable for use as a donor in chemical syntheses of sialylated oligosaccharides. The derivatized sialylated aryl thioglycosides are prepared in high yields, due to reduced number of chemical and purification steps involved in the process. Derivatized aryl thioglycosides useful as building blocks for the synthesis of biologically active sialylated oligosaccharides are also disclosed.

摘要:Methods for the synthesis of polycyclic aromatic hydrocarbons and synthesis platforms for performing such syntheses are provided. Methods and platforms are provided that allow for the synthesis of aza-polycyclic aromatic hydrocarbons by an expedient ring assembly. Methods and platforms allow for a modular approach to synthesis that provide multiple new C—C bonds in sequential pericyclic reactions, thus giving access to compounds with multiple axes of substitution.

标题 :Solid phase and combinatorial synthesis of substituted thiophenes and of arrays of substituted thiophenes

摘要:A solid phase method for the synthesis of a plurality of differently substituted thiophenes with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The thiophenes are prepared by reaction of a substrate-bound primary or secondary amine with a thiophosgene equivalent and reaction of the resulting intermediate with an acceptor-substituted acetonitrile in the presence of a base. Alkylation with an appropriate alkyl halide, followed by Thorpe-Ziegler-cyclization yields differently substituted, support-bound 3-aminothiophenes. These may be screened on the substrate or cleaved from the substrate and then screened in solution. Alternatively, the resin-bound 3-amino thiophenes or the synthetic intermediates can be subjected to further synthetic transformations (N-acylation, reduction) on the support, which permits the preparation of further therapeutically interesting compounds. The efficient synthesis of a wide variety of thiophenes using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiophene-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.
