摘要

通过阴离子立体钴（III）络合物催化对映选择性Ugi四组分/Wittig工艺的级联反应，一锅法合成了手性多功能恶唑框架。该方法可耐受包括醛、胺、羧酸和异氰基（三苯基磷酰）醋酸酯在内的复杂反应体系，生成具有良好对映选择性的手性2,4,5-三取代恶唑（高达93:7 er）。

Enantioselective construction of functionalized oxazoles via anionic stereogenic-at-cobalt(iii) complex-catalyzed Ugi-4CR/Wittig reaction sequences†

A one-pot synthesis of chiral multifunctional oxazole frameworks is accomplished via a cascade reaction involving an anionic stereogenic cobalt(iii) complex-catalyzed enantioselective Ugi four-component/Wittig process. This approach tolerates a complex reaction system that includes aldehydes, amines, carboxylic acids, and isocyano-(triphenylphosphoranylidene)acetates, yielding chiral 2,4,5-trisubstituted oxazoles with good enantioselectivities (up to 93 : 7 er).
