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%.
