摘要:The present invention describes the synthesis of silicon-containing monomers and copolymers. The synthesis of a monomer, trimethyl-(2-methylenebut-3-enyl)silane (TMSI) and subsequent synthesis of diblock copolymer with styrene, forming polystyrene-block-polytrimethylsilyl isoprene, and synthesis of diblock copolymer Polystyrene-block-polymethacryloxymethyltrimethylsilane or PS-b-P(MTMSMA). These silicon containing diblock copolymers have a variety of uses. One preferred application is as novel imprint template material with sub-100 nm features for lithography.

标题 :Systems and methods for preparation of highly reactive alkali metal dendrites for the synthesis of organolithium reagents

摘要:Systems and methods for formation of highly reactive alkali dendrites are provided. For example, in some embodiments alkali metals are dissolved in ammonia to form metal electrides after which the ammonia is removed via vacuum to reveal highly activated metal surfaces in the form of crystalline alkali dendrites. The alkali dendrites can mimic powders but have the advantage of being freshly prepared from inexpensive and readily available metal sources. These uniquely activated metals exhibit enhanced reactivity comparatively to similar off the shelf sources of the corresponding metals. For example, the dendrites can have about 100 times greater surface area than conventional metal sources and/or be about 19 times more reactive than powders that serve as the industry standard for the preparation of organometallic compounds. After surface activation, these metals can be used to prepare various organometallic reagents.

摘要:Two syntheses are provided; one for the preparation of (3R,4R)-4-(hydroxymethyl)pyrrolidin-3-ol, and other for the preparation of (3S,4R)-4-(hydroxymethyl)pyrrolidin-3-ol. (3R,4R)-4-(hydroxymethyl)pyrrolidin-3-ol is prepared using the achiral ylide prepared from benzylamine instead of phenethylamine (Scheme 3) which provides a crystalline intermediate. The synthesis of (3S,4R)-4-(hydroxymethyl)pyrrolidin-3-ol is achieved from (S)-diethylmalate as described in Scheme 4. A process for preparing camphor sultam is also provided.

摘要:The subject invention provides catalytical compounds/complexes, compositions comprising such compound/complex, synthesis of the compounds/complexes, and methods of using such compounds/complexes as catalysts in, for example, carbon isotope exchange (CIE) on target bioactive molecules. Methods that allow CIE directly on drug candidates are of great importance to chemistry, biology, and medicine. Especially valuable are catalytic procedures that rely on a limited collection of available labeled materials. The instant method comprises converting a methyl group to terminal â•?CH2 utilizing transfer dehydrogenation catalysts to enable V-based olefin metathesis, followed by a hydrogenation step. The one-pot strategy allows the formal methylation/demethylation sequence and can be applied to an assortment of alkyl-containing compounds.
