标题:通过在纳米范围内组织烷醇来提高水合氢离子催化脱水的速率
摘要:水合氢离子催化的烷醇脱水速率通过沸石孔的空间限制尺寸以及与其他烷醇的孔内分子间相互作用而增强.孔径小于沸石 Bea 的沸石 Mfi 对仲烷醇,3-庚醇和 2-甲基-3-己醇的脱水具有较高的速率,这是由于 Mfi 更严格的限制中的较低活化焓抵消了较小的正值.激活熵.对于叔烷醇 2-甲基-2-己醇的脱水,Bea 中的活性高于 Mfi,这主要归因于通过稳定 C β-H过渡态与周围醇分子的孔内相互作用来降低活化焓.总体而言,我们表明沸石限制的积极影响源于烷醇与过渡态的限制和分子间相互作用提供的过渡态的稳定,这受到限制的大小和e1途径中烷醇的结构的影响脱水.

摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.
