Sažetak

Bicyclic succinic anhydrides alkylated at the α-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.

Ključne riječi
