2-oxo-2-p-tolylacetaldehydehydrate Use and Manufacturing
General procedure: Arylglyoxals 1 (0.2 mmol), alkynes 2 (0.2 mmol), Cu(OAc)2 (10 mol%) and AcOH (20 mol%) were dissolved in 4 mL toluene and stirred at 80 C for 4h in a sealed tube equipped with an O2 balloon. Monitored by TLC, when the reaction was completed, the reaction mixture was cooled to room temperature, then quenched with saturated NH4Cl solution and extracted with dichloromethane. The organic layer was washed with brine and dried over anhydrous Na2SO4 and directly subjected to silica gel column chromatography (hexane/dichloromethane=1:1) to afford SI-4.EXAMPLE A22 Allyl 6-Bromo-6-[1-hydroxy-2-(4-methylphenyl)-2-oxoethyl]penicillanate
