A total synthesis of pseudouridimycin (1) was accomplished featuring an unusual oxime Ugi-type multicomponent condensation to simultaneously construct the dipeptide moiety of this peptidyl nucleoside antibiotic. In this synthetic route 1 is readily accessible via a longest linear sequence of 9 synthetic steps from pseudouridine. This strategy can be applicable to a variety of pseudouridimycin analogues.
