摘要:Low-temperature organometallic nucleation and crystallization-based synthesis methods for the fabrication of semiconductor and metal colloidal nanocrystals with narrow size distributions and tunable, size- and shape-dependent electronic and optical properties. Methods include (1) forming a reaction mixture in a reaction vessel under an inert atmosphere that includes at least one solvent, a cationic precursor, an anionic precursor, and at least a first surface stabilizing ligand while stirring at a temperature in a range from about 50° C. to about 130° C. and (2) growing nanocrystals in the reaction mixture for a period of time while maintaining the temperature, the stirring, and the inert-gas atmosphere.

标题 :Preparation of biologically active compounds from substantially pure enantiomers of 2-azabicyclo 2.2.1!hept-5-en-one
发明人：EVANS CHRISTOPHER THOMAS; ROBERTS STANLEY MICAHEL
权利人:CHIROSCIENCE LTD
摘要:Lactams of 1-amino-3-carboxylic acid cyclic compounds are provided in enantiomeric form, together with an enantiomer of the corresponding ring-opened amino-acid or ester, by reaction of the racemic lactam with a novel lactamase. The products are useful in the synthesis of chiral carbocyclic nucleotides. The enantiomer is preferably 2-azabicyclo 2.2.1!hept-5-en-3-one.

摘要:The invention provides for production of nanoparticles dispersed in polymers where the nanoparticles include metals and metal oxides/sulfides that provide enhanced properties (e.g. higher refractive index) to the material. The nanoparticles are typically formed in situ within the polymer. Typically the nanoparticles are in the form of nanocrystals.

标题 :Synthesis, structure and use of bisoxazolidines for asymmetric catalysis and synthesis

摘要:One aspect of the invention relates to chiral bisoxazolidines and their use in asymmetric catalysis. The chiral bisoxazolidines are a novel class of compounds that is expected to find multiple applications, for example, in asymmetric synthesis. For example, a bisoxazolidine ligand enabled the catalytic enantioselective alkynylation and alkylation of a range of aromatic and aliphatic aldehydes, generating chiral propargylic alcohols and secondary alcohols in high yields and enantiomeric excess.
