Abstract
Abstract The reaction of 1,1,1,5,5,5-hexafluoro-2,4-pentanedione with ( R )-phenylglycinol was found to proceed via intermediate formation of ( R , 4 E , 6 Z )-5,7-bis-(trifluoromethyl)-2,3-dihydro-3-phenyl-1,4-oxazepine which further underwent a base-catalyzed 1,3-proton shift reaction followed by [1,2] Wittig rearrangement giving rise to 2,4-bis-(trifluoromethyl)-6-phenylpyridine.
