标题:钼酸钴催化剂上木质纤维素酮选择性加氢脱氧生产烯烃
摘要:烯烃是生产燃料和许多有用化学品的重要原料.在此,钼酸钴(comoo 4)首次通过环境友好的蒸发方法合成,并且在通过木质纤维素衍生的酮的选择性加氢脱氧(hdo)生产烯烃方面表现出优异的催化性能.表征结果表明,Comoo 4优异的催化性能归因于其更大的比表面积,更好的孔结构,更高的氧空位(或mo 5+物种)浓度,更高的酸强度和更高的酸位浓度.在优化的反应条件下,4-庚酮几乎完全转化为庚烯,并且在co/mo原子比为0.8的comoo 4催化剂上(记为comoo 4-0.8 ),获得了较高的庚烯碳收率(96%).).Comoo 4催化剂对于其他木质纤维素酮(例如丙酮,丁酮,2-戊酮,3-戊酮,环戊酮,环己酮,5-壬酮和苯乙酮)选择性hdo生成其相应的烯烃也具有活性.

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.

标 题 :Method for the synthesis of deoxypyridinoline
发明人：HATCH ROBERT P
权利人:BAYER AG
摘要:Disclosed is a method for the chemical synthesis of deoxypyridinoline (DPD). The synthesis involves the preparation of a protected 3-hydroxypyridinium starting with a Nα-protected lysine and a 5,6-epoxy-2-N-protected-O-protected-(2S)-2-aminohexanoate with subsequent deprotection to provide the desired DPD.

摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.
