Preparation of Protected β-Keto Aldehydes from β-Keto Esters via Selective Reduction of Acyl(alkoxycarbonyl)ketene Dithioacetals
The acyl(alkoxycarbonyl)ketene dithioacetals 2 prepared from the corresponding β-keto esters 1 in almost quantitative yield are reduced selectively with magnesium in methanol and subsequently dealkoxycarbonylated to give protected β-keto aldehydes 4 in hi
