Diols 4a and 4b are commercially available [for a synthesis of 4a, see: Mash, E. A.; Nelson, K. A.; Van Deusen, S.; Hemperly, S. B. Org. Synth., Coll. Vol. VIII 1993, 155-161]. Diol 4c was used for diastereoselective cyclopropanations

However, the experimental and spectroscopic data of 4c were not reported. 4c was prepared from 2,3-O-isopropylidene-L-threitol [2,3-O-Isopropylidene-L-threitol is readily available from (+)-diethyl tartrate in two steps. We used the procedure described by Holy, A. (Collect. Czech. Chem. Commun. 1982, 47, 173-189; acetalization by triethyl orthoformate and acetone followed by reduction of the ethyl ester groups by sodium borohydride in absolute ethanol)] by double alkylation with 2-(bromomethyl)naphthalene followed by acetonide cleavage (see Experimental).

4 resulted in cleavage of β-naphthylmethoxy groups to 2-methylnaphthalene. Use of other reducing agents (ammonium formate, Pd/C, MeOH or sodium borohydride in the presence of copper sulfate) led to complete decomposition.

The catalytic hydrogenation of diazide 6c to afford diamine 3c was also successful in isopropanol at 45°C, but THF was found to be more convenient. The catalytic hydrogenation of diazide 6a to diamine 3a was carried out in methanol, see Ref. 4, but THF is also an excellent solvent.

In this case, palladium on carbon was a totally ineffective catalyst. However, when Pearlman's catalyst was used, diamine 6d was contaminated by colloidal palladium, which could not be removed.

Recently, the vicinal diamines 3a-d were used for the preparation of salen Mn(III) complexes as catalysts for the enantioselective epoxidation of unfunctionalized alkenes: Scheurer, A.; Mosset, P.; Spiegel, M.; Saalfrank, R. W. Tetrahedron 1999, 55, 1063-1078.

Crude acetonide 8 was obtained along with residual 2-(bromomethyl)naphthalene and was used as such for the next step. Subsequent acetonide cleavage yielded crystalline diol 4c which was easily purified.
