Cyclopentadiene, benzene and cycloheptatriene were transformed to functionalized meso-diols. The resulting meso-diols or their corresponding meso-diacetates were subjected to enzymatic asymmetrizations using enzymes, particularly lipases, in organic

The potent glucosidase inhibitor 1-deoxynojirimycin was synthesized from L-sorbose using a short synthesis and only one protecting group. The last step, which constituted the removal of an acetonide protecting group and an intramolecular reductive am
