Popis: | Pd(0)-catalyzed arylation of the aryl-substituted α-allenic alcohols with hypervalent iodonium salts afforded substituted trans-epoxides. Alternatively, arylation of the alkyl-substituted α-allenic alcohols in the presence of K 2 CO 3 afforded syn-diol cyclic carbonates and trans-epoxides in the presence of Cs 2 CO 3 . |
