摘要:The present invention provides unified synthesis of the C1-C19 building blocks of halichondrins and analogs thereof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hybridized carbon. The provided efficient selective coupling reactions can allow easy access to the C1-C19 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.

标 题:Phosphorus-containing caprolactone monomers for synthesis of flame retardant polycaprolactones
发明人：CAMPBELL ERIC J; CZAPLEWSKI SARAH K; KOBILKA BRANDON M; WERTZ JASON T
权利人:IBM
摘要:A process of forming a flame retardant monomer includes forming a hydroxyl-functionalized caprolactone molecule, and reacting the hydroxyl-functionalized with a phosphorus-containing flame retardant molecule to form a flame retardant-functionalized caprolactone monomer. A flame retardant monomer includes at least one moiety derived from a hydroxyl-functionalized caprolactone molecule and at least one phosphorus-containing flame retardant moiety. A flame retardant polymer includes at least two flame retardant monomer repeat units, each flame retardant monomer repeat unit including at least one moiety derived from a hydroxyl-functionalized caprolactone molecule and at least one phosphorus-containing flame retardant moiety.

摘要:The present invention is directed to a processes for the synthesis of trans isomer of 4,6-disubstituted-tetrahydro-furo, thieno, pyrrolo and cyclopenta-[3,4][1,3]dioxoles (Formula I). The process comprises the steps of: (a) obtaining a compound of Formula II, which is a mixture of cis and trans-diastereomers, and (b) chemically decomposing the compound of Formula II in a solution comprising a solvent and an acid that is a hydrogen donor or an electron pair acceptor, whereby the cis diastereomer is decomposed and the compound of Formula I is obtained. The compounds prepared by the present invention are useful in treating diseases or conditions associated with platelet aggregation and/or platelet activation.
