Stereoselective synthesis of (E)-2-(1-hydroxyalkyl)alk-2-enenitriles via(Z)-1-cyanoalk-1-enyl anion intermediates
Abstract
Fluoride ion-induced desilylation of (E)-2-trimethylsilylalk-2-enenitriles affords(Z)-1-cyanoalk-1-enyl anion intermediates, which are trapped by carbonyl compounds to give (E)-2-(1-hydroxyalkyl)alk-2-enenitriles with 100% retention of the configuration.
