  Zeolite β-Induced Rearrangement of Alkoxybenzyl Allyl Ethers to Aldehydes and Ketones. 5.¹ Variation of the Allylic Moiety

  摘要：

  Allylic PMB ethers rearranged in the presence of zeolite beta to form 4-arylbutanals or 5-arylpentanones depending on the substituent pattern of the allylic moiety. Best results were obtained with substrates carrying simple substituents in the allylic 2-position, but a couple of substrates lacking a 2-substituent also rearranged. More functionalized substituents in this position were not tolerated. A propargyl PMB ether and a homoallylic PMB ether rearranged as well, but the products were mixtures of isomeric olefins. The 4-arylbutanals 2c and 2e and the 5-arylpentanone 2j were cyclized in PPA to give naphthalene and dihydronaphthalene derivatives, respectively.

• A metal-free desulfurizing radical reductive C–C coupling of thiols and alkenes

  An intermolecular reductive C–C coupling of electrophilic alkyl radicals and alkenes has been developed. Thiols were used as both hydrogen-donating reagents and alkyl radical precursors in the presence of triethyl phosphite and radical initiator. A wide range of alkenes, including styrenes, and aliphatic olefins were well tolerated in this transformation. Mechanistic studies indicated that a phosphite

  The mechanism for the novel zeolite beta catalyzed rearrangement of alkoxybenzyl allyl ethers to aldehydes and ketones has been investigated by use of cross reactions and deuterium labeling. The reaction is mainly intramolecular and may be described as a nucleophilic attack of the double bond on the electrophilic benzylic carbon of the ether-Lewis acid complex, followed by a 1,2-hydride (or alkyl) migration.
