• γ-Lactone Formation in the Addition of Benzenesulfonyl Bromide to Diene and Enyne Esters
  作者：Chen Wang、Glen A. Russell

  DOI：10.1021/jo982388a

  日期：1999.3.1

  The gem-dialkyl effect has been used to promote the formation of functionalized gamma-lactones in the addition of benzenesulfonyl bromide to diene and enyne esters. Introduction of 3 mol % of pyridine into the reactions increases the yields of lactones produced from tertiary esters. Formation of the C-alpha-C-beta bond of gamma-lactones has been achieved in both C-alpha-->C beta and C-beta-->C-alpha radical cyclization directions.
