tertiary benzylic positions of methylbenzylethers or unsymmetrical dibenzyl ethers and is also applicable to direct allylation, alkynylation, and cyanation reactions, as well as the azidation. The present methodologies provide not only a novel chemoselectivity but also the advantage of shortened synthetic steps, due to the direct process without the deprotection of the methyl and benzylethers.
be used as a general ligand system to support sequential hydrogen atom transfer and oxygenation at a mononuclear iron center. This new type of reactivity not observed in nature delivered Mukaiyama hydration products of various styrene derivatives.
