  Modular Approach to Saturated and α,β-Unsaturated Ketones

  摘要：

  2-Fluoro-6-pyridinyloxy derivatives of 2-ethoxyvinyl carbinois react with radicals derived from xanthates by an addition fragmentation pathway to give highly functionalized ketones after acid hydrolysis. 1,4-Diketones are readily accessible by this approach. alpha,beta-Unsaturated ketones can be obtained by starting with geminal acetoxy xanthates prepared by addition of a simpler xanthate to vinyl acetate.

• Tri- and Tetrasubstituted Functionalized Vinyl Sulfides by Radical Allylation

  2-Fluoropyridinyl-6-oxy- precursors derived from phenyl vinyl sulfide react with radicals generated from xanthates via an addition–elimination process to furnish the corresponding vinyl sulfides in good yields. This convergent method is operationally simple and enables a straightforward synthesis of the difficult to access tetrasubstituted vinyl sulfides. Vinyl sulfides were used as more robust enol ether surrogates

  A recently discovered radical fragmentation of 2-fluoro-6-pyridinoxy derivatives allows a new highly stereoselective and convergent route to (E)-vinylsulfones from allylic alcohols. Reductive desulfonylation or nickel-catalyzed couplings furnish di- and trisubstituted (E)- and (Z)-alkenes.

• Elimination versus Ring Opening: A Convergent Route to Alkylidene-Cyclobutanes
  作者：Julien Brioche、Michal Michalak、Béatrice Quiclet-Sire、Samir Z. Zard

  DOI：10.1021/ol202798r

  日期：2011.12.2

  Functionalized alkylidene-cyclobutanes have been prepared from 2-fluoropyridinyl-6-oxy precursors derived from vinyl cyclobutanols by a radical addition elimination process. A wide range of functional groups is tolerated, and the alkylidene-cyclobutanes can be further elaborated Into cyclopentanones. The limitation of this approach resides in the competition with opening of the cyclobutane ring.
