  Regioselective synthesis of substituted 1-indanols, 2,3-dihydrobenzofurans and 2,3-dihydroindoles by electrochemical radical cyclization using an arene mediator

  摘要：

  Electrochemical reduction of haloarenes carrying 2-(1-hydroxybut-3-enyl), 2-allyloxy or N-allyl-N-methylamino group in the presence of phenanthrene as a mediator generated the corresponding aryl radicals and gave the corresponding 5-exo cyclization products in good yields. Higher regio- and stereoselectivities than those of usual radical cyclization using AIBN-Bu3SnH were achieved. (C) 2003 Elsevier Ltd. All rights reserved.

  Up the tempo: The intramolecular addition of oxime radicals to CC bonds was achieved by using DEAD and TEMPO to give 4,5‐dihydroisoxazoles as a result of a CO bond‐forming, 5‐exo‐trig cyclization. γ,δ‐Unsaturated ketoximes also reacted to afford cyclic nitrones through CN bond formation. The reactions offer a metal‐free approach for the vicinal difunctionalization of unactivated alkenes.

  aerobic oxidative cyclization of β,γ-unsaturated hydrazones for the preparation of pyrazole derivatives has been developed. The hydrazonyl radical promoted the cyclization, along with a concomitant C═C bond cleavage of β,γ-unsaturated hydrazones. This process has been verified via several control experiments, including a radical-trapping study, an 18O-labeling method, and the identification of the possible

• Facile Preparation of Allylzinc Species from Allyl Bromides and Unactivated Zinc Induced by a Catalytic Amount of Aluminum Chloride and Their Reactions with Carbonyl Compounds and Acetals.

  The effects of Lewis acids (ZnCl2, AlCl3, BF3, and TiCl4) on the generation of allylzinc species from allyl bromide and unactivated zinc powder in dry tetrahydrofuran (THF) were examined by trapping the organozinc compound with benzaldehyde, that is, Grignard-type allylation of the aldehyde. Among the Lewis acids employed, AlCl3, was found to be the promoter of choice. The allylzinc species preformed in the presence of a catalytic amount of AlCl3 effectively allylated carbonyl compounds. Various aromatic and aliphatic aldehydes as well as ketones were converted into homoallylic alcohols in good to excellent yields. Under the reaction conditions employed, ester, hydroxy, acetal, and aromatic nitro and halide groups were tolerated. In the case of α, β-unsaturated carbonyl compounds, selective 1, 2-addition was observed. Substituted allyl bromides such as prenyl, crotyl, cinnamyl, and 2-cyclohexenyl bromides were smoothly converted to the corresponding allylzinc compounds, which reacted with carbonyl compounds to give substituted homoallylic alcohols in excellent yields. The diastereoselectivity in crotylation, cinnamylation, and 2-cyclohexenylation depended upon the structures of both the organic metals and the electrophiles. The origin of the observed selectivity is discussed. The allylation of dimethyl and cyclic acetals accompanied with carbon-oxygen bond cleavege also proceeded in excellent yields provided that two equivalents of AlCl3 was present.

  InI-mediated direct allylation of carbonyl compounds with allylic alcohols proceeded smoothly with catalytic amounts of Ni(acac)2 and PPh3 to give the corresponding homoallylic alcohols in high yields. Allylindium compounds were shown to be the real allylating agents in the present system. Substituted allylic alcohols gave branched homoallylic alcohols with syn-selectivity irrespective of the geometry
