Yield:944695-76-5 91%

Reaction Conditions:

with C42H62ClO3PPd;sodium phosphate in toluene at 50; for 24 h;

Steps:

General procedure for palladacycle 1-catalyzed addition reactions of arylboroxines with aldehydes

General procedure: To a vial containing aldehyde (0.25 mmol), arylboroxine (0.167 mmol), K3PO4 (0.75 mmol) and palladacycle 1 (0.00125-0.0000125 mmol) (palladacycle 1 was added in a toluene solution: 1 mg/mL solution of palladacycle 1 in toluene was freshly prepared and 1-40 μL of this solution was added to the reaction system by microsyringes) was added toluene (1 mL). After the mixture was stirred at 50-90 oC for 20-60 hours, the reaction was quenched by adding a small amount of water. Column chromatography on silica gel with ethyl acetate/hexane (v/v=1:10) afforded the alcohols.
