Abstract
A new, simple method for the synthesis of enol phosphates by base-mediated tandem reaction of α-aryloxyacetophenones with phosphonates is described. In the presence of Cs2CO3, a variety of α-aryloxyacetophenones smoothly underwent the sequential O-P bond-forming/C-O bond cleavage/isomerization tandem reaction with phosphonates at room temperature, providing the corresponding enol phosphates in moderate to excellent yields.
Key words
base - tandem reaction - α-aryloxyacetophenone - phosphonate - enol phosphate
