They are produced from tert-butyloxirane and the corresponding phenols.
专利号:US-7220870-B2 优先权日:1995-03-14 标 题:Hydrolytic kinetic resolution of cyclic substrates 发明人:JACOBSEN ERIC N; TOKUNAGA MAKOTO; LARROW JAY F 权利人:HARVARD COLLEGE 摘要:The present invention relates to a process for stereoselective or regioselective chemical synthesis which generally comprises reacting a nucleophile and a chiral or prochiral cyclic substrate in the presence of a non-racemic, chiral catalyst to produce a stereoisomerically- and/or regioisomerically-enriched product. The present invention also relates to hydrolytic kinetic resolutions of racemic and diastereomeric mixtures of epoxides.
专利号:WO-2024056715-A1 优先权日:2022-09-15 标 题:Epoxidation of porous amine-based phenylic polymer resins and methods of use for carbon dioxide capture 发明人:WANG HAO; ALBANI DAVIDE; AZTIRIA TOMAS; AMORUSO GIORDANO 权利人:SVANTE TECH INC; CLIMEWORKS AG 摘要:A solid epoxidized aminated porous phenylic polymer without the use of a porous silica support structure is described herein along with its method of synthesis and its application to the adsorption of carbon dioxide (CO2) from a feed gas. As compared to the prior art, this epoxidized porous aminated phenylic polymer is lower cost and exhibits improved long-term stability and reliability to degradation by oxygen at the elevated temperatures of temperature swing adsorption of CO2 and subsequent desorption at temperatures in the range of 120°C or greater. In addition, the active materials of this solid adsorbent do not leach from the polymer when exposed to water or condensing steam at the elevated temperatures of temperature swing adsorption. An illustrative example of the use of 1,2-propylene oxide (epoxypropane) to epoxidize a solid porous phenylic aminated resin substrate based upon a simple one-step reaction at room temperature is described herein. This epoxidized IER exhibits approximately a three-fold improvement in lifetime upon exposure to oxygen in dry air at 110°C-120°C as compared to the non-epoxidized polymeric starting material.
