Singlet-Oxygen-Mediated One-Pot Synthesis of 3-Keto-tetrahydrofurans from 2-(β-Hydroxyalkyl) Furans
摘要:
Photooxygenation of 2-(beta-hydroxyalkyl) furans affords, in one synthetic operation and in high yields, 3-keto-tetrhydrofuran motifs via intramolecular Michael-type addition to the 1,4-enedione intermediate.
