Cr. Johnson et al., CHEMOENZYMATIC SYNTHESIS OF TRANS-4,5-DIHYDROXYCYCLOPENT-2-ENONES - CONVERSION TO D-1-DEOXYNOJIRIMYCIN, Journal of the Chemical Society, Chemical Communications, (11), 1995, pp. 1139-1140
5-Bis(tert-butyldimethylsilyloxy)cyclopent-2-enone 8 and (4R,5S)-trans
-4,5-di(benzyloxy)cyclopent-2-enone 20 are prepared by equilibration o
f the corresponding cis derivatives; enone 8 is transformed into the g
lucosidase inhibitor, D-1-deoxynojirimycin 14.
