标题 :Aminohydroxylation of alkenes
发明人：MEE SIMON PETER HAROLD; LUXENBURGER ANDREAS; HARRIS LAWRENCE DANIEL
权利人:MEE SIMON PETER HAROLD; LUXENBURGER ANDREAS; HARRIS LAWRENCE DANIEL; VICTORIA LINK LTD
摘要:The invention relates to a process for the aminohydroxylation of alkenes using N-oxycarbamate reagents, e.g. N-acyloxycarbamate, N-alkyloxycarbonyloxycarbamate and N-aralkoxycarbonyloxycarbamate reagents. The invention particularly relates to an intermolecular aminohydroxylation reaction that can be carried out in the absence of added base. The invention also relates to novel N-oxycarbamate reagents that are stable crystalline materials. The process of the invention is useful in the synthesis of compounds having a vicinal amino alcohol moiety, such as biologically active compounds.

标 题:Synthesis and use of oxa-spirodiphosphine ligand
发明人：ZHANG XUMU; CHEN GENQIANG; HUANG JIAMING
权利人:SHENZHEN CATALYS TECH CO LTD
摘要:The present invention relates to the technical field of chiral synthesis, and specifically provides the synthesis and use of a new type of oxa-spirodiphosphine ligands. The bisphosphine ligand is prepared with oxa-spirobisphenol as a starting material after triflation, palladium catalyzed coupling with diaryl phosphine oxide, reduction of trichlorosilane, further palladium catalyzed coupling with diaryl phosphine oxide, and further reduction of trichlorosilane. The oxa-spiro compound has central chirality, and thus includes L-oxa-spirodiphosphine ligand and R-oxa-spirodiphosphine ligand. The racemic spirodiphosphine ligand is capable of being synthesized from racemic oxa-spirobisphenol as a raw material. The present invention can be used as a chiral ligand in the asymmetric hydrogenation of unsaturated carboxylic acids. The complex of the ligand with ruthenium can achieve an enantioselectivity of greater than 99% in the asymmetric hydrogenation of methyl-cinnamic acid.

标 题:Chemical synthesis and anti-tumor and anti-metastatic effects of dual functional conjugate
发明人：LIU GANG; ZHAO NAN; MA YAO
权利人:LIU GANG; ZHAO NAN; MA YAO; SHENZHEN SALUBRIS PHARM CO LTD
摘要:The present invention discloses chemical synthesis, anti-tumor and anti-metastatic effects of a dual functional conjugate as shown by formula I. Specifically, paclitaxel or docetaxol is linked with muramyl dipeptide derivative to form a conjugate, thus dual anti-tumor and anti-metastatic effects are achieved by combination of chemotherapy and immunotherapy. The present invention also discloses that paclitaxel or docetaxol and muramyl dipeptide derivative conjugate is synthesized by combination of solid-phase and solution-phase synthesis, and said conjugate can be used in manufacture of anti-tumor medicaments as proved by reliable bioassays.
