An efficient catalytic preparation of synthetically useful new β-borylated enamides was achieved under relatively mild conditions via a regioselective iridium-catalyzed C(sp2)?H borylation. The method features broad substrate scope, good functi

The aldol-type addition of 1,3-dibenzyl-dihydrouracil 2 to 2,3-O-isopropylidene-D-glyceraldehyde 3 was examined in different solvents and under Lewis acid catalysis in order to establish the stereochemical preferences. A stereodivergent synthesis of 5-trihydroxypropyl-dihydrouracil derivatives 4 and its C-5 epimer 5 was realized. The synthesis of ureido polyols 8 and 10 was obtained via the reductive ring opening of the templates 4 and 5.
