Selective deoxygenation of allylicalcohol can be successfully carried out by the formation of alkoxyalkyl ether (EE or MOM), followed by Pd(dppe)Cl2-catalyzed reduction with LiBHEt3. (+)-S-Lavandulol has been efficiently synthesized by the application of this protocol to the diol derived from the Pb(OAc)4-promoted oxidative ring-opening of (−)-R-carvone. This deoxygenationmethod is general and selective
通过形成烷氧基烷基醚(EE或MOM),然后用LiBHEt 3催化Pd(dppe)Cl 2催化还原,可以成功地进行烯丙醇的选择性脱氧。通过将该方案应用于衍生自Pb(OAc)4促进的(-)- R-香芹酮的氧化开环的二醇,已有效地合成了(+)- S - Lavandulol。该脱氧方法对烯丙基醇是通用的和选择性的。
