Diastereocontrolled Construction of Pactamycin’s Complex Ureido Triol Functional Array
[Image: see text] An advanced intermediate in a projected synthesis of pactamycin has been prepared. Early installation of the C1-dimethylurea functionality allows for its participation in a diastereoselective, chelation-controlled addition of organometal nucleophiles to the C5 prochiral ketone. Four of the molecule’s six stereocenters are set with a ketone functional handle provided for subsequent manipulation
