Chemoselective protection of α-Ketoacids by direct annulations with oximes

Flores, Melissa A.,Bode, Jeffrey W.

supporting information; experimental part, p. 1924 - 1927 (2010/07/04)

Figure presented Oximes and α-ketoacids undergo an unexpectedly facile and chemoselective annulation to afford 2,5-dihydrooxazole 3-oxides. The resulting cyclic nitrones serve as chemically and configurationally stable masked α-ketoacids that can be easil
