Yield:23783-42-8 90%
Reaction Conditions:
with pyridinium p-toluenesulfonate in methanol at 0 - 20; for 16 h;
Steps:
5.B 2,5,8,1 1-Tetraoxatridecan- 13-ol (5-2A)
To a solution of 2-(2,5,8,l l-tetraoxatridecan-13-yloxy)tetrahydro-2H-pyran 5-lA (280 mg, 0.96 mmol) in MeOH (5 mL) was added PPTS (24 mg, 0.096 mmol) and stirred at 0 °C to RT for 16 hr. The reaction mixture was concentrated under reduced pressure to get crude compound. Obtained crude was purified using silica gel column chromatography 5% MeOH in DCM to afford 5-2A (180 mg, 0.87 mmol, 90% yield) as a pale yellow liquid
