标题:通过s-o键裂解的过渡金属催化的磺酸盐转化:烷基芳基醚和二芳基醚的合成
摘要:磺酸盐(一种通用的医药中间体)的催化转化通常基于c-o键的裂解.然而,在本文中,我们发现通过过渡金属催化的s-o键断裂,磺酸盐发生了罕见的转变,在镍催化剂的存在下,烷基磺酸盐可以通过分子内脱硫c-o偶联形成芳基烷基醚.同时,芳基磺酸盐的性能相似,得到由钯络合物催化的二芳基醚.这种转变可以容忍各种各样的功能.对照实验表明2-吡啶基对于促进反应是必需的.交叉实验证明,这种转化可能部分地通过分子间途径进行.

权利人:ABBOTT LAB
摘要:An efficient deoximation technique for use in synthesis of erythromycin derivatives, involving aryl thioimine intermediates is disclosed. The aryl thioimine intermediates can be utilized in a method for protecting a ketone of a ketone-containing erythromycin derivative as a thioimine; a method for deoximating an oxime-containing erythromycin derivative, or a method for preparing a 6-O-alkyl erythromycin derivative. Presently preferred erythromycin derivatives have a C-9 oxime or a C-9 ketone.
