New route to 4-aminocyclopent-2-en-1-ols: Synthesis and enantioselective rearrangement of 4-amino-substituted cyclopentene oxides

A new route for the asymmetric synthesis of 4-aminocyclopent-2-en-1-ols (90% ee) for carbocyclic nucleoside analogue synthesis is described. The approach involves the stereoselective preparation of cis 4-amino-substituted cyclopentene oxides and subsequent chiral base-mediated rearrangement to the corresponding allylic alcohols. Full details on the synthesis and stereoselectivity of epoxidation of 4-amino-substituted cyclopentenes are presented. (C) 2000 Elsevier Science Ltd.

Synthesis and enantioselective rearrangement of 4-amino-substituted cyclopentene oxides

Several N-mono- and diprotected alkenes have been prepared and the stereoselectivity of their epoxidation has been investigated: N-monoprotected alkenes give cis epoxides preferentially (due to hydrogen bonding directed epoxidations) whereas N-diprotected alkenes produce trans epoxides exclusively (due to steric effects). Chiral lithium amide base-mediated rearrangement of a cis-monoprotected epoxide generated the corresponding amino-cyclopentenol in good yield and with an enantiomeric excess of 60%.
