## Abstract 3โ€Ketotetrahydrofuran (II) has been obtained spectroscopically as well as gasโ€chromatographically pure. A major modification in the dichromateโ€sulphuric acid oxidation of the starting alcohol (I) has almost doubled the yield to 60%. The chromium trioxideโ€pyridine oxidation of (I) is de
