Gabriel's synthesis
WebIn the case of Gabriel synthesis, after SN2 reaction by a strong base, the alpha-carbon acquires sp2 characteristic due to resonance with neighboring esters. This of course means the electrophile (our desired R group) can attack the alpha-carbon on either side with an approximately equal probability, resulting in racemic mixture. I hope this helps.

WebThe total synthesis of peramine, an alkaloid produced by a fungus that protects grasses against grazing by mammals and insects, successfully employed the Gabriel synthesis … The Gabriel synthesis is a chemical reaction that transforms primary alkyl halides into primary amines. Traditionally, the reaction uses potassium phthalimide. The reaction is named after the German chemist Siegmund Gabriel. The Gabriel reaction has been generalized to include the alkylation of sulfonamides and imides, followed by deprotection, to obtain amines (see Alternative Gabriel reagents).
