Chemoselective Hydrolysis of Ester Bonds in the Presence of Baker's Yeast
摘要:
The catalytic effect of baker's yeast on the hydrolysis of aliphatic esters in p-acetoxybenzoates is described. The chemoselective character of this reaction enables the selective protection of the hydroxyl group in p-hydroxybenzoic acid derivatives.

The photopromoted, Ni-catalyzed acceptorless dehydrogenation esterification of phenols and aromatic aldehydes has been achieved in an oxidant- and external photosensitizer-free manner. This reliable and atom-economical transformation was tolerant to a wide range of functional groups and proceeded efficiently to give various aryl benzoates in moderate to high yields. Additionally, this photocatalytic
