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...
