Stereoselective Synthesis of 2,5-Dialkyl-3-(phenylsulfonyl) Tetrahydrofurans via Cyclisation of Z-Sulfonyl-substituted Homoallylic Alcohols

Craig, Donald,Ikin, Neil J.,Mathews, Neil,Smith, Alison M.

, p. 7531 - 7534 (1995)

Z-Sulfonyl-substituted homoallylic alcohols 3 underwent highly anti-selective base-mediated 5-endo-trig cyclisation reactions to give 2,5-dialkyl-3-phenylsulfonyl tetrahydrofurans anti-2.A simple steric model is proposed to account for the high selectivit
