标 题 :Synthesis of alkenes from enamines via hydroboration
发明人：GORALSKI CHRISTIAN T; SINGARAM BAKTHAN; BROWN HERBERT C
权利人:PURDUE RESEARCH FOUNDATION; DOW CHEMICAL CO
摘要:Alkenes are prepared by the hydroboration of enamines followed by an elimination reaction to form the alkene. This process has wide applicability and is useful for the stereospecific synthesis of [Z] isomers. It is preferred to use 9-borabicyclo[3.3.1 nonane as the hydroborating agent and to use methanol to catalyze the elimination reaction.

标 题 :Preparation and uses of conjugated solid supports for boronic acids
发明人：HALL DENNIS G
权利人:UNIV ALBERTA
摘要:The invention provides novel solid supports comprising dihydroxyalkyl aminoalkyl and dihydroxyalkylaminobenzyl groups, and methods for making and using them. The supports are particularly useful for immobilizing and derivatizing functionalized boronic acids for use in solid phase synthesis, such as those used in combinatorial chemistries. The compositions and methods of the invention are also useful as scavenger solid supports, e.g., in solution-phase parallel synthesis of small molecule libraries, and for use in resin-to-resin transfer reactions via phase transfer of solid supported boronic acids under both aqueous and anhydrous conditions. The methods of the invention provide convergent solid-phase synthesis of symmetrically or unsymmetrically functionalized compounds, such as biphenyl compounds. Also provided are synthesizer devices, e.g., semiautomated parallel synthesizers.

摘要:The present invention belongs to the field of chemistry and chemical engineering, and disclosed are a type of Si-O-Si framework bridged multi-nuclear boron catalyst, a preparation method therefor, and a use thereof. The Si-O-Si framework of the Si-O-Si framework bridged multi-nuclear boron catalyst can be a linear structure of Si-O-Si, a ring structure of Si-O-Si, or a cage structure of Si-O-Si. The feasibility of multiple types of topological structures provides controllability for the synthesis of multi-nuclear boron. The multiple Lewis acid centers of this type of system can better activate monomers and stabilize active species, reflecting the synergistic effect of multiple boron centers. The multi-nuclear boron catalyst of the present invention is mainly used in ring-opening polymerization and copolymerization to prepare diverse low-carbon polymers, such as polyethers, polyesters, polycarbonates, etc.

摘要:The inventive subject matter relates to novel processes for making an epoxy alcohol from an aldehyde, comprising the steps of: (a) adding (i) an organozinc compound or (ii) divinylzinc compound and an diorganozinc compound to said aldehyde in the presence of a first catalyst to form an allylic alkoxide compound; and (b) epoxidizing said allylic alkoxide compound in the presence of an oxidant and a second catalyst.
