Аннотация

The Kröhnke reaction of 2ω-bromoacetylphenoxathiin and 2-ω-bromophenoxathiin 10,10-dioxide,
through N-ylide and S-ylide intermediates, leading to the corresponding glyoxals, was described. The
condensation reaction of 2-ω-bromoacetylphenoxathiin with aromatic o-hydroxy aldehydes and further
cyclization to new furan derivatives was also performed. The new compounds were characterized
through elemental analysis and spectral data (IR, 1
H NMR and 13
C NMR).
