1,3-Propanediol synthesis from carbohydrates

Although 1,3-propanediol (HOCH2CH2CH2OH) can now be prepared from carbohydrate feedstocks (Section 30.8), it can also be prepared from petroleum feedstocks. Devise a synthesis of HOCH2CH2CH2OH from CH3CH=CH2, a product of petroleum refining. 

Biomass-based alcohols could also be employed directly as substrates in N-alkylation reactions, making the hydrogen autotransfer method more practical. In 2011, Martin-Matute and co-workers reported a [Cp IrCl2]2-catalyzed method for synthesis of secondary aminosugars from primary aminosugars with simple alcohols and primary carbohydrate alcohols (Eq. 20) [106]. In 2009, Stephens, Marr and coworkers reported that a one-pot bio- and chemo-catalytic process could be used for direct conversion of crude glycerol from biodiesel production to valuable secondary amines in a biphasic system without intermediate separation of 1,3-propanediol...
