Tetrachloro-o-benzoquinone in Organic Synthesis: A Novel Synthetic Route to Pyrazolo<1,5-c><1,3>benzoxazines and 5,7-Disubstituted-4-hydroxycoumarins
Nawwar, Galal A. M.
Journal of Chemical Research, Miniprint, 1991 , # 12 p. 3139 - 3155
Abstract
A novel synthesis of dihydropyrazolo<1,5-c><1,3>benzoxazines and their corresponding pyrazolo<1,5-c><1,3>benzoxazines utilizing tetrachloro-o-benzoquinone - as a dehydrogenating agent - is described.Also, this simple method of dehydrogenation succeeds in converting ethyl 4,6-diaryl-2-acetoxy-5,6-dihydrobenzoates to their corresponding 2-acetoxybenzoate derivatives which can be cyclized to afford 5,7-disubstituted coumarins.The scope and limitation of this method are also discussed.
