(R)-2-Tosyloxypropanal (4) was prepared from D-mannitol in a 7-step sequence (51% overall yield). Addition of dialkyl phosphonates to 4 in the presence of titanium isopropoxide and the subsequent treatment with DBU stereoselectively afforded, in one-pot, fosfomycin dimethyl (5a) and dibenzyl (5b) esters both in 58% isolated yield.

(Matrix Presented) A new chiral ferrocenyl diphosphine ligand 3 was synthesized from readily available D-mannitol. Rh-complex with this ligand showed high enantioselectivity and reactivity in the asymmetric hydrogenation of dehydroamino acid derivatives and itaconic acid derivatives. Up to over 99% ee and 10 000 TON were achieved with this catalytic system.
Highly Flexible Synthetic Routes to Functionalized Phospholanes from Carbohydrates
Yan, Yuan-Yong,RajanBabu
, p. 900 - 906 (2007/10/03)
Highly functionalized phospholanes 15, 17, and 26 and the corresponding diastereomers in which the configurations of the phospholane carbon-2 and carbon-5 are inverted can be readily prepared from D-mannitol by displacement of the appropriate dimesylate or cyclic sulfate with dilithium-phosphide reagents. The diols from which these ligands are prepared can also be converted into diarylphosphinite ligands. A route to related monophosphines bearing hemilabile tert-butylthio groups is also described. Complexes of these ligands and of related deprotected derivatives are potentially useful for enantioselective catalysis in organic and aqueous media.
