Abstract
and C-allylgalactopyranosides 1c and 1d, -C-allylazaglucopyranoside 1e and -C-allylfruttofuranoside 1f were hydroformylated at low temperatures affording a mixture of linear and branched aldehydes in regioisomeric and diastereoisomeric ratios depending on the starting alkene. The results obtained have allowed us to study the influence of the different structural features of the sugar moiety on the regio- and diastereoselectivity of the hydroformylation reaction.File in questo prodotto:
