Synthesis and Alcoholysis of α-Alkylated Cyclopentane and Cyclohexane Fused Succinic Racemic Anhydrides in the Presence of Chiral Bases
摘要:
Bicyclic succinic anhydrides alkylated at the alpha-position have been prepared and submitted to alcoholysis in the presence of alkaloid bases. Anhydrides with a cyclopentane fused ring, open only from the less hindered side, generating monoesters of >80 % ee, whereas cyclohexane fused anhydrides undergo parallel kinetic resolution, producing both regioisomeric monoesters.
