four oxazoline mediated reactions, including coupling of ortho-(methoxy)aryloxazolines with Grignard reagents, butyllithium based ortho-lithiation of aryloxazolines, stereocontrolled Ullmann couplings of bromonaphthyloxazolines, and ethoxyvinyllithium hexamethylphosphoric triamide complex based ortho-lithiation of aryloxazolines.
(S)-棉酚(S)-1是棉籽的黄色颜料,已通过完全不对称合成得到。四个恶唑啉介导的反应突出了导致(S)-棉酚(S)-1的序列,包括邻-(甲氧基)芳基恶唑啉与格利雅试剂的偶联,芳基恶唑啉的丁基锂基邻位锂化,溴萘甲恶唑啉的立体控制Ullmann偶联以及乙氧基乙烯基锂六甲基磷酸三酰胺络合物基于芳基恶唑啉的邻位锂化反应。
