摘要:The present invention relates to an enzymatic synthesis of 4′-ethynyl-2′-deoxy nucleosides and analogs thereof, for example EFdA, that eliminates the use of protecting groups on the intermediates, improves the stereoselectivity of glycosylation and reduces the number of process steps needed to make said compounds. It also relates to the novel intermediates employed in the process.

标 题:Precursor chemistry for quantum dot synthesis enabling temperature-independent modulation of reactivity
发明人：HAN HEE-SUN; PARK JOONHYUCK
权利人:UNIV ILLINOIS
摘要:Provided herein are methods of making a high-quality quantum dot (QD), including by providing anion precursor chemistry that enables chemical modulation of precursor reactivity, thereby, allowing independent optimization of reaction temperature and precursor reactivity to systematically grow high quality QDs and by providing specially configured tunable precursors and related chemistry to facilitate separate reaction pathways for nucleation and growth, thereby accessing heat-up based synthesis of high-quality QD, including core-shell QDs. The methods may include providing a base-QD and a first anion or cation precursor having a composition comprising an anion or a cation element, respectively, and a modification agent. At least one add-layer is grown on the base-QD at a growth temperature, thereby making the high-quality QD comprising the base-QD and the at least one add-layer. At least one add-layer may have a composition comprising an add-layer cation element and an add-layer anion element.

发明人：THIELE SVEN K H; MONROY VICTOR M; WILSON DAVID R
摘要:Random or block co- or terpolymers produced by using metal complex catalysts in a reaction of one conjugated diene monomer with one aromatic Random or block co- or terpolymers produced by using metomers with one aromatic α-olefin or terpolymers of one conjugated diene monomer with one aromatic α-olefin and one aliphatic α-olefin by using metal complexes comprising metals of group 3 to 10 of the Periodic System of the Elements in combination with activators and optionally a support material. More particularly the metal complexes used for the synthesis of co- or terpolymer are lanthanide metals. Even more particularly diene monomer(s) and aromatic α-olefin monomer(s) such as, but not limited to, butadiene and styrene or isoprene and styrene are copolymerized giving random or block copolymers or butadiene, styrene and isoprene are terpolymerized giving random or block terpolymers using metal complexes comprising lanthanide metals in combination with activators and optionally a support material. Preferably random co- or terpolymers are formed.
