Rt. Brown et al., Synthesis of chiral polyfunctionalised cyclopentanes from the Diels-Alder adduct of furan and maleic anhydride, J CHEM R-S, (4), 2000, pp. 176-178
Chiral polyfunctionalised cyclopentanes have been readily obtained in simil
ar to 65% enantiomeric excess via a stereospecific Wagner-Meerwein rearrang
ement induced by bromination of derivatives of the exo-cis Diels-Alder addu
ct of furan and maleic anhydride, combined with desymmetrisation of a meso
intermediate by pig liver esterase.
