  Z-Selective Intramolecular Horner−Wadsworth−Emmons Reaction for the Synthesis of Macrocyclic Lactones

  摘要：

  When the substrates (ArO)(2)P(O)CH2CO2-CHO (Ar = Ph, o-t-BuPh) were added to a THF solution containing 3 equiv of NaH at 0 degrees C or NaI-DBU at rt over 1-10 h, the Intramolecular Horner-Wadsworth-Emmons reaction proceeded efficiently to give the 12-18-membered-ring lactones in 69-93% yields with 89-100% Z selectivity. On the other hand, (EtO)(2)P(O)CH2CO2-CHO gave the 13-18-membered-ring lactones in 52-82% yields with 89-99% E selectivity using LiCl-DBU in MeCN or THF.

  acid with either ω-alkenols or α,ω-diols, followed by ozonolysis or Dess―Martin oxidation as appropriate, underwent intramolecular Julia―Kocienski olefination when treated with DBU. Macrocyclic α,β-unsaturated lactones of between 12- and 19-membered ring sizes were formed successfully using this tactic (24―44% yield, Z/E ≥ 3.5:1); however, diolides were selectively produced from precursors intended
