  Synthesis and Functionalization of 3-Alkylidene-1,2-diazetidines Using Transition Metal Catalysis

  摘要：

  An efficient two-step synthesis of a wide range of 3-methylene-1,2-diazetidines has been developed through application of a Cu(I)-catalyzed 4-exo ring closure. The double bond of this new class of strained heterocycle can be functionalized in a stereocontrolled manner by using palladium-catalyzed Heck reactions. Moreover, chemoselective reduction of 3-alkylidene-1,2-diazetidines gives access to saturated 1,2-diazetidines and vicinal diamines.

• Synthesis of Ketones and Esters from Heteroatom-Functionalized Alkenes by Cobalt-Mediated Hydrogen Atom Transfer
  作者：Xiaoshen Ma、Seth B. Herzon

  DOI：10.1021/acs.joc.6b01709

  日期：2016.10.7

  Cobalt bis(acetylacetonate) is shown to mediate hydrogen atom transfer to a broad range of functionalized alkenes; in situ oxidation of the resulting alkylradical intermediates, followed by hydrolysis, provides expedient access to ketones and esters. By modification of the alcohol solvent, different alkyl ester products may be obtained. The method is compatible with a number of functional groups including

  DOI：10.1021/ol026671e

  日期：2002.9.1

  [reaction: see text] The (methoxycarbonylamino)methyl radical can be readily generated from its PhSe precursor and undergoes preferential 6-exo-spiro cyclization when PhSO(2) is attached at the distal alkene carbon. This property was applied to the synthesis of the racemic and optically active spirocyclic alkaloid sibirine.

• A radical based addition–elimination route for the preparation of indoles

  日期：——

  Indoles, including tricyclic derivatives, are produced by cyclisations of aryl radicals onto vinyl halides followed by elimination of halide radical and tautomerism of the resulting product; the aryl radicals are produced using “clean methodology” either by reaction of iodide ions with arenediazonium salts or by reaction of phosphorus-centred radicals with aryl iodides.

  日期：2017.12

  Lanthanide(III)-catalyzed aryl-Claisen rearrangement of substrates bearing halo-substituted allyl groups, specifically 2-bromoallyl aryl ethers, afford ortho-2-bromoallylphenols. Aryl ether substrates were synthesized from brominated allylic alcohols via Mitsunobu reaction, Cu(II)-catalyzed arylation using potassium aryltrifluoroborate salts, or SNAr reaction. Aryl-Claisen rearrangements proceeded in moderate to
