REACTION PATHS OF 1,3-OXAZOLINIUM SALTS WITH STABILIZED CARBANIONS

Reaction of stabilized carbanions with 3-methyl-2-phenyl-1,3-oxazolinium triflate occurs both C5 and C2 sites with a regioselectivity depending partially on steric effects.The reaction at C2 site can result in the formation of 1,4-oxazepin derivatives.
