The Aldol-Tishchenko reaction is a tandem reaction involving an Aldol reaction and a Tishchenko reaction. In organic synthesis it is a method to convert aldehydes and ketones into 1,3-hydroxyl compounds. The reaction sequence in many examples starts from conversion of a ketone into an enolate by action of lithium diisopropylamide (LDA). The mono-ester diol is then converted into the diol by a hydrolysis step. With both the acetyl trimethylsilane and propiophenone as reactants, the diol is obtained as a pure diastereoisomer.
Famous quotes containing the word reaction:
“In contrast to revenge, which is the natural, automatic reaction to transgression and which, because of the irreversibility of the action process can be expected and even calculated, the act of forgiving can never be predicted; it is the only reaction that acts in an unexpected way and thus retains, though being a reaction, something of the original character of action.”
—Hannah Arendt (19061975)
