Abstract: Synthesis of 3-acyl-5,6-dihydro-1,4-oxathiines has been achieved via reactions of thiiranes and α-diazo-β-1,3-dicarbonyl compounds under microwave and copper sulfate-assisted conditions. The current method provides a direct and simple strategy in efficient preparation of 3-acyl-1,4-oxathiines from readily… read more here.

Abstract: Abstract We investigated the reactions of substituted N-acyl-2,3-dihydro-4-pyridones with TosMIC reagent under various basic conditions to generate novel pyrrole products. These products were then transformed to substituted azaisoindoles in a couple of steps. read more here.
