A mixture of alcohols 1 or 3 (0.6 mmol) and bis(methoxypro-
pyl) ether (1.8 mmol) was added to a 5 mL round-bottom flask
with an oxygen balloon at room temperature, then the con-
tents were stirred at 120 °C. The reaction typically took
1
2 hours. The progress of this oxidation was monitored by TLC
or GC-MS. Upon the completion of the reaction, the reaction
mixture was cooled down to room temperature. The reaction
mixture was purified by silica gel column chromatography to
afford the desired 2 and 4.
