WebWeinreb amide 211b was then subjected to reduction with DIBAL-H at −78°C to afford aldehyde 216 without observable reduction of the ester group. However, when this step was scaled up, a complex mixture of inseparable products was obtained. Fortunately, when Schwartz's reagent was employed, reduction of the Weinreb amide afforded aldehyde … WebCompounds 15a–j were prepared using a cross-coupling reaction between 14 and the corresponding boronic acids/esters, along with reduction of the methyl ester group with LiAlH 4 or DIBAL-H .
