3-[(TERT-BUTYLDIMETHYLSILYL)OXY]-1-PROPANAL synthesis

11synthesis methods
3-(tert-Butyldimethylsilyloxy)propanol (1.90 g, 10 mmol) was dissolved in dichloromethane (20 mL), and Dess-Martin reagent (6.36 g, 15 mmol) was added under ice bath. After stirring at room temperature for 4 hours, saturated aqueous sodium bicarbonate solution was added to quench, and the mixture was diluted with dichloromethane (100 mL). The mixture was washed twice with saturated aqueous sodium bicarbonate solution and once with brine. The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The mixture was purified by silica gel column chromatography to obtain 1.55 g of 3-[(tert-Butyldimethylsilyl)oxy]-1-propanal with a yield of 82%.

Yield:89922-82-7 66%

Reaction Conditions:

with 4-methylmorpholine N-oxide;silica gel in dichloromethane;acetonitrile

Steps:

1.1 Step 1
Step 1 Tetrapropylammonium perruthenate (0.18 g, 5.3 mmol) was added to a mixture of methylene chloride (20 mL) and acetonitrile (2 mL) containing 3-(tert-butyldimethylsilyloxy)-propanol (2 g, 0.01 mmol), N-methylmorpholine N-oxide (1.76 g) and 4 ? molecular sieves. The reaction mixture was stirred at RT overnight and then filtered through a pad of silica gel. The filtrate was concentrated under vacuo to afford 3-(tert-butyldimethylsilyloxy)-propionaldehyde (1.3 g, 66%).
