资源简介:
This study describes an organocatalytic
kinetic resolution of racemic
secondary nitroallylic alcohols (2) combined with simultaneous
desymmetrization of prochiral cyclic anhydrides (1).
The experimental results revealed that enantioselective alcoholysis
of 3-substituted glutaric anhydrides afforded hemiesters (3) with high levels of enantioselectivities (up to 99% ee) in the
presence of cinchonidine-derived thiourea catalyst (IV). The highly optical enrichment (up to 95% ee) of (S)-nitroallylic alcohols (2) was recovered.
