Synthesis of chiral pyrrolidine and pyrrole derivatives through the chemoselective Dieckmann reaction of α,β-aminodiesters
摘要:
alpha,beta -Aminodiesters were allowed to react with t-BuOK in THF at -78 degreesC. The chemoselectivity of the Dieckmann cyclization was controlled by the nature of the substituents R-3 and R-4, allowing the preparation of pyrrolidine or pyrrole derivatives.
