Facile formation of N-acyl-oxazolidinone derivatives using acid fluorides

Schindler, Corinna S.,Forster, Patrik M.,Carreira, Erick M.

supporting information; scheme or table, p. 4102 - 4105 (2010/11/19)

A mild method is presented for the formation of N-acylated oxazolidinones that employs acid fluorides and mild bases, such as iPr 2NEt and NEt3. Optimized reaction conditions for two types of substrates have been developed utilizing either the oxazolidinone itself or the corresponding in situ generated O-silyloxazolidinones resulting in the formation of the desired N-acylated products in high yields of up to 98%.
