标题:均相锰催化剂对羧酸的选择性加氢硼化
摘要:将羧酸催化还原成相应的醇是具有挑战性的任务,对于生产各种增值化学品而言,这一任务非常重要.在此,已开发出锰催化的羧酸的化学选择性氢硼化反应,其在25oc时具有较高的周转数(> 99 000)和周转频率(> 2000 H-1).该方法显示了具有高化学选择性的电子和空间分化底物的耐受性.重要的是,可以有效地还原脂族长链脂肪酸,包括生物质衍生的化合物.机理研究表明,该反应通过插入和键易位类型机制,通过活性锰氢化物物种的形成而发生的.

摘要:A more environmentally friendly synthesis method of 4-bromo-2-(4′-ethoxyphenyl)-1-chlorobenzene with simplified steps provides a more effective synthetic strategy for producing key intermediates of SGLT-2 inhibitors such as dapagliflozin, sotagliflozin, and ertugliflozin. In the presence of trifluoroacetic anhydride, 5-bromo-2-chlorobenzoic acid and phenetole are selected to complete a direct acylation reaction under the catalysis of boron trifluoride diethyl etherate, and triethylsilane is added thereinto without treatment for one-pot reaction to obtain a target compound 4-bromo-2-(4′-ethoxyphenyl)-1-chlorobenzene.

发明人：HALL DAVID A
权利人:LILLY CO ELI
摘要:This invention encompasses 7-(S)-acylamino-3-acetoxymethyl-3-cephem-4-carboxylic acid sulfones and the epimerization process for making them. The epimerization process employs an organic nitrogen base reagent having a pKa between about 9.0 to about 11.5. The compounds of this invention are intermediates in the synthesis of 1-oxa-β-lactam antibiotics.
