Chemical production of 1,3-butanediol from biomass-derived compounds was first reported by 1,4-anhydroerythritol hydrogenolysis over a Pt-WOx/SiO2 catalyst. The reaction proceeded by ring opening hydrogenolysis of 1,4-anhydroerythritol followed by selective removal of secondary OH groups in 1,2,3-butanetriol, and an overall 1,3-butanediol yield up to 54% was then obtained. The performance of the Pt-WOx/SiO2 catalyst for 1,4-anhydroerythritol hydrogenolysis was closely correlated with that for glycerol hydrogenolysis to 1,3-propanediol. The optimized Pt-WOx/SiO2 (Pt: 4 wt% and W: 0.94 wt%) catalyst showed 57% yield of 1,3-propanediol.

PROBLEM TO BE SOLVED: To provide a production method for an erythritol hydrogenolysis product, including hydrocracking the erythritol on mild conditions to efficiently obtain butane-mono, di or triol.SOLUTION: The production method for the erythritol hydrogenolysis product comprises supplying to a reactor hydrogen and a material solution containing the erythritol and reacting in the reactor the erythritol with hydrogen in the presence of a catalyst to obtain the erythritol hydrogenolysis product, wherein, as the catalyst, a catalyst provided by supporting iridium on a carrier is used, and as the reactor, a trickle bed reactor is used. As the catalyst, at least one metal ingredient selected from the group consisting of rhenium, molybdenum, tungsten and manganese is preferably used together with the catalyst carrying the iridium on the carrier.
Conversion of racemic allylic hydroperoxides into corresponding chiral 1/2,3-triols by using catalytic OsO4 and chiral cinchona ligands in the absence of co-oxidant

For the first time, removal of oxygen atoms from allylic hydroperoxide functionality and reintroduction to the double bond was achieved using catalytic OsO4 and chiral cinchona alkaloid derivatives in an acetone-water mixture to give corresponding chiral 1/2,3-triol with an enantioselectivity up to 99% ee. The hydroperoxide group was used as both a co-oxidant and a source of hydroxyl groups. This protocol is thought to have potential to provide opportunities for chiral synthesis of 1/2,3-triols from corresponding allylic hydroperoxides in the absence of co-oxidant in one stage for the first time in the literature.
