Diastereocontrolled Construction of Pactamycin’s Complex Ureido Triol Functional Array
摘要:
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.
