Ph3P CH3 Ph H3C H3C Eto2C The Fischer esterification reaction synthesizes an ester via a nucleophilic acyl substitution reaction The stereochemistry the alcohol oxygen that makes the nucleophilic attack. The Mitsunobu reaction, on the other hand, allows the synthesis of an ester in which the stereochemistry of the alcohol is inverted. The reaction involves a carboxylic acid and an alcohol, as well as triphenylphosphine and an azo compound termed diethyl azodicarboxylate DEAD). As with the Fischer esterification, H20 is formally...
