摘要：

'I' is all the hype: A twofold excess of iodoarene in the title reaction leads to ortho-quinols in good yields, whereas organocatalytic versions of this reaction enable subsequent epoxidation in a regio- and diastereoselective fashion. Chiral iodobiarenes led to enantioselectivities up to 50 % ee. m-CPBA=meta-chloroperoxybenzoic acid. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
