Abstract:

3-(Polyfluoroacyl)chromones undergo heterodiene cycloaddition to 3,4-dihydro-2H-pyran, 2,3-dihydrofuran and ethyl vinyl ether under mild conditions, producing novel fused pyrans with high stereoselectivity and in good yields. Some of these pyrans were transformed into 2-R-F-containing pyridines on treatment with ammonium acetate in ethanol. (c) 2008 Elsevier Ltd. All rights reserved.
