Functionalized oxazolidinones are important organic molecules that exhibit interesting biological activities. The oxazolidinonemoiety can, for example, be found in pharmaceuticals, such as Locostatin, a Raf-kinase inhibitor and natural products (Scheme 1a). Synthetically, N-acylated oxazolidinones have mostly been used as chiral auxiliaries, first popularized by Evans and have been employed in different asymmetric transformations 2 such as aldol, alkylation, Diels-Alder reactions and Michael additions and in total synthesis 7 (Scheme 1a) and still attracts considerable attention within the synthetic community today. The general synthesis of N-acylated oxazolidinones proceeds by deprotonation normally using a strong base, such as n-BuLi, in combination with an acid chloride or anhydride (Scheme 1b). However, the use of highly reactive substrates, which requires special precautions as well as the usage of strong bases, capable of epimerizing chiral oxazolidinones at the C-5 position limits these protocols. Alternative methods includes the use of coupling reagents, 10 acyl fluorides, 11 carbonylazoles, DMAP, metal catalysis, and electrochemistry. However, these procedures still requires highly reactive reagents, coupling reagents, high reaction temperatures and reagents in excess in order to drive the reaction to completion. Thus, adverse to the principles of green chemistry, these methodologies are not sustainable in terms of atom economy, energy efficiency, less hazardous synthesis and catalysis. Clearly, a more environmentally benign acylation of oxazolidinones would be highly desirable (Scheme 1c).
