(R)-2,5-Dihydro-3,6-dimethoxy-2-isopropylpyrazine

CAS: 109838-85-9

(R)-2,5-Dihydro-3,6-dimethoxy-2-isopropylpyrazine and its enantiomer (S)-2,5-Dihydro-3,6-dimethoxy-2-isopropylpyrazine are also known as Schöllkopf chiral auxiliaries or Schöllkopf reagents, and are used to produce optically pure α-amino acids via asymmetric synthesis. The Schöllkopf reagent can be deprotonated at the prochiral α-carbon, and the resulting enolate is trapped with electrophiles to yield adducts with high (typically > 95% d.e.) diastereoselectivity. The enolate is essentially planar, and the steric bulk of the isopropyl group directs the incoming electrophile to attack from the opposite face, yielding trans adducts. A wide range of electrophiles including alkyl halides, alkyl sulfonates, acyl chlorides, aldehydes, ketones, epoxides, thioketones and enones can be used. Hydrolysis, typically under mild acidic conditions, yields the non-substituted amino acid with high (typically > 95 e.e.) enantiopurity.
