Article abstract of DOI:10.1039/cc9960002697

Triphenylbismuthonium 2-oxoalkylide 2, generated in situ from salt 1 in THF at low temperature, readily reacts with 1,2-dicarbonyl compounds 3 to give 2,3-diacyloxiranes 4 or 2-acyl-3-hydroxytropones 5 depending on the structure of the electrophiles invol
