synthesis of heterocyclic compounds. Therefore, a lot of efforts have been devoted to developing these highly electrophilic units. Wasserman et al. reported an unique synthetic route in which triphenylphosphorane ylides 2, valuable precursors to vicinal tricarbonyls, are introduced in a convergent manner and then oxidized under mild reaction conditions (Scheme 1).
