Radicals derived from β-ketoesters can, depending on the
position of the unpaired electron, represent synthetic equivalents to the
high energy and elusive alkynyl radicals or to the stabilised and
relatively unreactive propargyl radicals by application of the xanthate
transfer reaction followed by nitrosative cleavage of the corresponding
isoxazolinones.
